Purchase order approval limits in Zoho Books, in short

You set purchase order approval limits in Zoho Books from Settings, under Purchase Orders, on the Approvals tab. Multi-Level Approval sends every order through a fixed chain of up to 10 approvers. To approve by amount, use custom approval rules that check the order total. Small orders then pass quickly and large ones reach a senior person.

An approval limit is the highest order value one person may approve on their own. Zoho Books has no single field called "limit". You build the limit from rules that look at the order and decide who must approve it. The rest of this guide shows both methods, gives a worked example and lists the points where these rules usually fail.

Approvals in Zoho Books are now set per module. You can switch them on for purchase orders without switching them on for invoices or bills. A community user once asked for exactly that, approval only for purchase orders rather than every purchase transaction. The Zoho Books guide to Multi-Level Approval confirms that you enable it module by module. If you are still choosing an accounting system, our overview of Zoho Books for UK businesses covers the wider product.

Approval terms in Zoho Books: approver, level, submitter and final approver

Zoho Books uses a small set of approval terms. Learn them before you configure anything, because the settings screens use them without explanation.

These are the terms you will meet:

Purchase order: the document that records what you intend to buy, from which vendor and at what price.
Bill: the payable document that records what you owe a vendor once goods arrive and the vendor invoices you.
Submitter: the person who creates a transaction and sends it for approval.
Approver: a user with approval access, who can check and edit a transaction before approving it.
Level: one step in a Multi-Level Approval chain. The order goes to the Level 1 approver first, then Level 2, and so on.
Final-level approver: the last person in the chain. Their approval completes the process.
Final approver: a role with its own permissions. The Zoho Books transaction approval FAQ explains what a final approver can do.

One detail matters for limits. An approver can edit a transaction before approving it, according to the Zoho Books help on transaction approval. That means the person approving an order can also change its value. Keep that in mind when you decide who sits at each level.

Choosing an approval type for purchase orders: none, simple, multi-level or custom

The approval type decides whether order value can change who approves. Zoho offers four choices for purchase orders: No Approval, Simple, Multi-Level and Custom. The Zoho Procurement help lists the same choices and sets No Approval as the default.

Approval type	Who approves	Can it vary by amount?	Suits
No Approval	Nobody. Orders go straight to Draft and can be sent.	No	Very small teams where the buyer is also the owner
Simple	One approver for every order	No	A business with one budget holder
Multi-Level	Up to 10 approvers in a fixed order	No. Every order follows the same chain.	Firms that want two or more sign-offs on every order
Custom	The approver named by the rule the order matches	Yes. Rules can test the total and other fields.	Firms with spending limits by amount or department

Multi-Level Approval is the easiest to set up, but it treats a small order and a large one the same. If your finance policy says "managers approve up to a set amount, directors above it", you need custom rules. Many businesses start with Multi-Level Approval and move to custom rules once approvers complain about signing off small orders.

Multi-Level sends every order up the same chain, while Custom rules route each order by its total. Multi-Level Approval / Custom approval. Who approves: Up to 10 approvers in a fixed order / Approver named by the rule the order matches; Link to order

Setting up multi-level approval for purchase orders, step by step

Multi-Level Approval suits you when every purchase order should pass the same people in the same order. The steps below follow the Zoho Books UK help page for Multi-Level Approval.

Go to Settings and open Purchase Orders.
Click the Approvals tab.
Select Multi-Level Approval under Approval Type.
Add an approver for each level. You can configure up to 10 levels.
Drag the levels into the order you want. Reordering changes the approval hierarchy.
Decide on the preference "Allow approvers to approve the transactions they create". Leave it unticked unless you have a reason.
Tick "Notify the submitter when a transaction is approved or rejected", so buyers know the outcome.
Save the settings.

Notifications follow the chain. Zoho Books sends the email and in-app notification to the Level 1 approver first. Once they approve, the next-level approver is notified, and so on through the hierarchy. A slow approver at Level 1 therefore holds up everyone behind them.

Keep the chain short. Each extra level adds a wait to every order, including the routine ones.

Setting approval limits by amount with custom approval rules

Custom approval rules are how you set real approval limits by amount in Zoho Books. You choose Custom approval on the same Approvals tab, under Settings and Purchase Orders, instead of Multi-Level Approval.

Each rule has two parts. The first is a condition, built from fields on the purchase order, such as the total, the vendor or the accounts on the line items. The second is an action. The action can send the order to a specific approver, approve it automatically or reject it automatically.

Several rules can run side by side. Each department can therefore have its own approver and its own thresholds. A rule for the warehouse can send orders to the operations manager, while a rule for marketing spend goes to the marketing lead.

Rules that hold up

Write the rules so that one order can only match one of them. Use clear bands, such as "total below X" and "total equal to or above X", with no gap and no overlap. If two rules can both match, nobody will be sure which approver Zoho Books chose until an order lands in the wrong inbox.

Write the limits down in your finance policy first, then copy the same figures into the rules. The policy and the system should never disagree on a number.

Worked example: three purchase order approval bands by amount

A worked example makes the custom rules concrete. The figures below are illustrative, not a recommendation. Suppose your policy sets three bands for purchase orders.

Rule 1, small orders: condition "Total is less than £500". Action: auto-approve.
Rule 2, medium orders: condition "Total is equal to or more than £500" and "Total is less than £5,000". Action: send to the operations manager.
Rule 3, large orders: condition "Total is equal to or more than £5,000". Action: send to the finance director.

Now follow one order. A buyer raises a purchase order for £2,400 of packaging. It starts in Draft. The buyer submits it for approval, and it matches Rule 2 only. The operations manager gets an email and an in-app notification.

Until the manager approves, the order cannot be sent to the vendor or converted to a bill. If the manager rejects it, they enter a reason. The buyer edits the order and resubmits it. Once approved, the buyer sends it and the status moves to Open.

Two checks complete the test. First, raise test orders at £499, £500, £4,999 and £5,000 and confirm each one reaches the right person. Boundary values are where bands most often go wrong. Second, ask the operations manager to edit a £4,800 order up to £5,200 during approval, and see what happens. Decide in advance whether that is acceptable.

Purchase order statuses before and after approval

Purchase order statuses tell you where each order stands, and approvals sit in front of them. When approvals are on for the Purchase Orders module, buyers must submit each order they create for approval. Zoho Procurement also lets buyers submit several orders at once.

The Zoho Books help on managing purchase orders lists these statuses:

Draft: the order has been created.
Open: the order has been sent to the vendor.
Partially Billed: the order has been billed for only some items.
Billed: the order has been converted to a bill.
Closed: the vendor accepted the order and it was converted to a bill.
Cancelled: the vendor rejected the order and you cancelled it.

Approvers need a place to work from. Zoho Books lets you view transactions pending approval and view the approval history of each one. You can also build a Custom View that filters purchase orders by your own criteria, then share that view with chosen users. A shared view of orders waiting for approval keeps the finance team and the approvers looking at the same list.

Bulk approval is available too. It saves time at month end, but it also makes rubber-stamping easy. Use it for small, routine orders, not for the large ones your limits were designed to catch.

Matching bills to purchase orders and receipts before you pay

Matching bills to purchase orders and receipts is the control that stops you paying for goods you never ordered or never received. A three-way match compares three documents: the purchase order (what you ordered), the receipt (what arrived) and the vendor's bill (what you are charged).

Zoho Books supports approvals beyond purchase orders. According to the Zoho Books transaction approval help, approvals are available on Purchase Receives, Bills, Payments Made and Vendor Credits, among other modules. You can therefore place a check at each stage, not only at the start.

A practical sequence looks like this:

The approved purchase order is sent to the vendor and becomes Open.
When goods arrive, someone records a purchase receive against the order.
The vendor's invoice arrives and you convert the order into a bill.
Before payment, compare the bill's quantities and prices with the order and the receipt.
Record the payment, with approval on Payments Made if you want a second check.

Watch for orders stuck at Partially Billed. That status means some items have been billed and others have not. A Custom View filtered on Partially Billed shows you open commitments that may still produce a bill.

Zoho Books warns on its approval help page that, without a verification step, mistakes can affect account balances and make discrepancies hard to track. Matching before payment is that verification step for purchases.

Where purchase order approval rules usually break down

Purchase order approval rules usually break down for organisational reasons, not technical ones. At Svennis we write the approval matrix on one page with the finance lead before anyone opens Settings. The failure we see most often is an approver who has left, with live orders still waiting at their level.

These are the common weak points:

Approvers who leave: the Zoho Books FAQ covers what happens when an approver becomes inactive or is deleted. Read it, and update your rules the day someone leaves.
Self-approval: the preference that lets approvers approve their own transactions defeats the purpose of a limit. Leave it off unless one person truly is the whole business.
Gaps or overlaps between bands: an order exactly on a threshold can fall into no rule or two rules.
Edits during approval: approvers can change an order before approving it, so a value can cross a band after the rule has chosen the approver.
Old assumptions about modules: approvals used to switch on for bills and purchase orders together. Check each module's Approvals tab separately.
Silent notifications: if the notification preferences are off, orders wait and nobody knows.

A two-level request appears often in the Zoho community. One user wanted two-level approval so that an accountant's approval could not be changed afterwards. Decide who may change an approved order before you go live, and test that behaviour.

Purchase order approvals for a UK company

For a UK company, purchase order approvals in Zoho Books are configured exactly as described above. The UK help centre at zoho.com/uk documents Multi-Level Approval and the transaction approval FAQ, so your team can follow British-English instructions that match the UK edition.

Set your limits in pounds sterling, using the same figures as your written spending policy. Your accountant or auditor will compare the two. If the policy says the finance director approves orders above a set amount, the custom rule should say the same amount, to the penny.

The approval history in Zoho Books gives you a record of each decision on each order. Keep that record useful. Give every approver their own login, never a shared one, so the history shows a real person.

Smaller UK firms often have a director who holds every role. In that case, a limit still helps. Auto-approve small orders and route large ones to a second director, so no large commitment rests on one person alone. If only one person can approve, write down why, and review the rule when the team grows.

Plan for holidays as well as leavers. Name a cover approver for each level before the summer and the Christmas break, when orders tend to pile up.

Next steps to set your purchase order approval limits

The next step is to decide your limits on paper, then configure and test them in Zoho Books. Work through this list in order:

Write your approval matrix: each band, its approver and a named cover.
Choose Multi-Level Approval if every order needs the same sign-offs, or Custom approval if limits depend on amount or department.
Configure the Approvals tab under Settings and Purchase Orders, with self-approval off and submitter notifications on.
Test orders at every boundary value and confirm each reaches the right approver.
Switch on approvals for Bills or Payments Made if you want a check before money leaves the account.
Build a shared Custom View of orders pending approval and of Partially Billed orders.
