What is purchase order and approval software?
Purchase order software is the system a company uses to turn a purchase request into an approved order and a paid invoice. Day to day, an employee submits a request, the tool routes it to the right approvers based on amount or department, checks it against a budget, issues a purchase order to the supplier and later matches the invoice to what was ordered and received. Finance teams, buyers, department heads and accounts payable staff all use it. Core capabilities include approval workflows, budget controls, invoice matching and links to the accounting system. Lighter tools avoid the weight of a full ERP.

How to choose the best purchase order software
Start with your approval process, because that is what the software must copy. Write down who requests, who approves at each amount, which budgets apply and how invoices are checked. Then compare tools on the criteria below, paying special attention to your accounting system, since a weak connection creates double entry. Finally, test two or three tools with a real purchase from request to invoice before you sign a contract.
PO creation and approval
This is the core function: turning a request into an approved purchase order. Strong tools let you build approval chains by amount, department or category and send the finished PO to the supplier automatically. Weak tools force every request through one fixed route. Check whether requisitions and custom approval routing are included in the plan you would buy.
- Ramp: Procurement add-on: PO management, custom intake.
- Tradogram: Purchase orders on Essentials; requisitions and custom approval routing as add-on/Premium.
- Precoro: Requisitions, POs, receipts, invoices with automated approvals.
- ProcurementExpress: PO requests with approvals, mobile apps for iOS and Android per GetApp listing.
- Procurify: Purchase orders with approval routing.
Budget control
Budget control stops overspending by comparing each request with the budget for its department or account code. Strong tools show remaining budget while the requester fills in the form and can block or flag requests that exceed it. Weaker tools only report on spend afterward. Some vendors sell budget tracking as an add-on.
- Ramp: Budget vs actual tracking on Plus and Enterprise.
- Tradogram: Real-time budget tracking as add-on or Premium.
- Precoro: Real-time budget tracking on Automation plan.
- ProcurementExpress: Requests are raised against predefined budgets and suppliers per GetApp listing.
- Procurify: Budgets and account codes.
Invoice matching
Invoice matching compares the invoice with the purchase order and, in a 3-way match, with the goods receipt. It catches wrong prices and quantities before payment and reduces AP errors. Strong tools automate the match and flag differences, while weaker ones leave it manual or limit it to higher tiers. Confirm which plan includes matching.
- Ramp: 3-way match against imported POs and item receipts under AP; also against Ramp POs with procurement; plan tier not clear.
- Tradogram: Receiving (GRN) as add-on or Premium.
- Precoro: 2- and 3-way matching on all plans.
- Stampli: Semi-automated 2 and 3-way match included; full automation by Billy available.
- Tipalti: 2-way and 3-way PO matching.
Accounting / ERP integrations
A purchase order tool must pass bills, vendors and account codes to your accounting system without retyping. Check support for QuickBooks, Xero, NetSuite, Sage or Dynamics and whether the sync is two-way. Some integrations are reserved for higher plans, so ask which connector comes with the plan you would buy.
- Ramp: Free: QuickBooks Online, Xero. Plus: NetSuite, Sage Intacct. Enterprise: Workday, Oracle Fusion.
- Tradogram: QuickBooks Online/Desktop, Xero, NetSuite, Sage, Dynamics 365 Business Central.
- Precoro: QuickBooks Online, Xero, NetSuite, Sage Intacct, Dynamics 365 BC, BILL.
- ProcurementExpress: QuickBooks (Basic), Sage 50 (Better), Sage 200 (Best), NetSuite and Dynamics (Enterprise)
- Procurify: QuickBooks Online, NetSuite, Sage Intacct, Dynamics 365.
Catalogs / punchout
Catalogs and punchout let requesters order from approved items and supplier sites instead of typing each line by hand. Strong tools offer internal item catalogs and punchout connections to suppliers such as Amazon Business or Staples, which speeds up ordering and keeps prices consistent. Many entry plans offer this only as an add-on.
- Tradogram: TradoCart PunchOut as add-on.
- Precoro: Item and service catalog on Core; PunchOut on Automation.
- ProcurementExpress: Amazon from Better; 100+ store from Best; custom store on Enterprise.
- Procurify: Product catalogs and PunchOut with Amazon Business, Staples, ZAGENO.
- Stampli: Preferred items; punchout not confirmed by the vendor.
Price / entry cost
Prices range from a flat monthly fee to charges based on users, managed spend or modules, and many vendors publish nothing. Compare the entry price and what it leaves out, such as requisitions, matching or integrations. Ask for a written quote that lists setup fees, add-ons and annual commitments.
- Ramp: Free; Plus $15 per user per month plus platform fee.
- Tradogram: From $99/month.
- Precoro: Published from $499/month.
- ProcurementExpress: Four tiers by monthly managed spend, $415 to $2,550, plus custom.
- Procurify: Quote only.
Trial / free tier
A free tier or trial lets you test your real approval flow before a sales conversation. Look for trials that include all features and need no card. Several vendors offer only demos or quote-based onboarding, so ask for a sandbox or pilot when no trial exists.
- Ramp: Free tier plus 30-day Plus trial.
- Tradogram: Not mentioned on pricing page.
- Precoro: Not mentioned on pricing page.
- ProcurementExpress: 14 days, full features, no card.
- Procurify: Demo and product tour only.

What purchase order and approval software costs per year for your size
For 20 users on the cheapest plan that fits, Tradogram costs $950 a year and ProcureDesk $9,960. Pick your own size: the order changes because free plans end, plans have user caps and per-user prices multiply differently.
| # | Tool | Plan and price basis | Per year |
|---|---|---|---|
| 1 | Tradogram | Essentials$79.2 per month, flat | $950 |
| 2 | Tipalti | Accounts Payable$99 per month, flat | $1,188 |
| 3 | Ramp | Plus$15 per user per month | $3,600 |
| 4 | Precoro | Core$499 per month, flat | $5,988 |
| 5 | ProcureDesk | Startup$830 per month, flat | $9,960 |
List prices per month as published on October 24, 2026, billed annually where the vendor shows both, promotions excluded. Full feature plan adds one-time onboarding fees in year one. Not in the calculation: ProcurementExpress, Procurify, Coupa, Stampli, Kissflow Procurement, Zip and Order.co (quote only, another pricing unit or a plan that does not fit this size). Payment fees come on top: Tipalti: Transaction-based fees extra (amounts not stated).
How far each price can climb
The entry price is rarely what you pay once the team needs more. Each line runs from a tool's cheapest paid plan to its most expensive published plan. ProcurementExpress grows 6.1x from $415 to $2,550, Tipalti 2.5x, while Ramp and Tradogram sell a single paid plan.
- ProcurementExpressBasic $415 to Best $2,550 per unit per month6.1x
- TipaltiAccounts Payable $99 to Mass Payments $249 per month2.5x
- PrecoroCore $499 to Automation $999 per month2x
- ProcureDeskStartup $830 to Growth $1,250 per month1.5x
Published plan prices only; quote-only plans are not on the scale. The scale is logarithmic so cheap and expensive tools fit on one line.
The price of single sign-on
If IT requires SAML single sign-on, the plan that includes it sets your real price, not the entry plan. 2 of the 3 tools that say where SSO sits charge more for it; 4 of 12 publish nothing about SSO, so ask before you budget.
- ProcureDesk+$420per unit per month: SAML SSO needs Growth ($1,250) instead of Startup ($830).
- Precoro+$500per unit per month: SAML SSO needs Automation ($999) instead of Core ($499).
- ProcurementExpressAskSAML SSO sits on Enterprise, which is quote only.
How PO and approval software pricing works
This category mixes flat fees, usage-based tiers and quote-only pricing, which makes comparison difficult. Many vendors do not publish add-on prices either. The patterns below are the ones to watch for when you build a first-year budget, and they are based on how the tools in this list present their plans. Use them as a checklist when you compare quotes, and keep the answers with your records for the renewal.
Flat monthly plans
Some vendors charge a fixed monthly fee by plan, from $99 to $830 per month in this list. Flat plans are easy to budget, but they often include a user bundle and charge more for extra users. Check what is included and what each added user costs.
Pricing by managed spend
One vendor here prices by the amount of spend managed per month, starting at $415 for up to $10k. This model grows with your purchasing volume. If your spend will increase, ask where the next tier begins.
Per-user fees plus platform fees
Other tools charge per user and add a platform fee based on team size, with the amount unpublished. The seat price alone understates the bill. Ask for the platform fee in the quote.
Modules sold separately
Requisitions, budget tracking, receiving, contracts and custom approvals can each be an add-on. A low entry plan can need several of them to be useful. Request a quote that lists every module you plan to use.
Quote-only pricing
Many vendors in this list only show contact sales. That can mean negotiable pricing, but it also hides what peers pay. Get at least three quotes on the same scope and ask for the multi-year price.
Costs that are easy to miss
Add-ons, usage fees and premium modules often decide the real bill. These are the paid extras the vendors list themselves.

Our recommendation
Pick the tool whose approval rules and accounting connection match your current process, then test it with one real purchase from request to paid invoice. Smaller companies can start with Tradogram, Precoro, ProcurementExpress or Ramp, while larger finance teams should look at Procurify, Stampli or Coupa. To keep costs under control, ask which features sit behind add-ons or higher plans and get the full price in writing.
Purchase Order and Approval Software: frequently asked questions
What is purchase order software?
Purchase order software lets teams request purchases, route them to approvers against budgets, issue POs and match invoices. It replaces email and spreadsheet approvals with a tracked workflow. SMB tools avoid enterprise ERP complexity.

Published entry prices include $99 per month for Tradogram, $415 per month for ProcurementExpress, $499 per month for Precoro and $830 per month for ProcureDesk billed annually. Ramp has a free tier, while Coupa, Procurify and Zip sell by quote only.
What do purchase order and approval software cost for a team of 20?
Calculated from published list prices: Ramp: Not computable: platform fee not published (users alone: 20 x $15 x 12 = $3,600 per year before the fee and annual discount); ProcurementExpress: Not per seat: Basic is $415 per month, so $4,980 per year (12 x $415), if spend stays under $10k managed per month; Tipalti: $1,188 per year platform fee on Accounts Payable ($99 x 12), identical for 20 users, plus transaction fees; ProcureDesk: Growth: $1,250 x 12 = $15,000/yr for 20 users.

Ramp (free plan, free trial) and ProcurementExpress (free trial), according to the vendors' sites on October 24, 2026.
