What off-contract spend looks like in healthcare
Off-contract spend (also called maverick or leakage spend) is any purchase made outside a negotiated supplier agreement or GPO contract, or at a price above the contracted rate.
Supplies are one of the largest costs a provider can control. Medical supplies consume 15% to 25% of operating expenses in outpatient and ambulatory settings, the second-largest controllable cost after labor.[3] That is why a few points of leakage matter far more here than in most industries.
It rarely starts as a policy breach. A fertility clinic runs short of culture media and orders from the rep who answers the phone. A new surgeon prefers a different suture brand. A site manager reorders from last year's email. Each decision is sensible on the day. Together they undo the contract.
Procurement Head
Negotiated a contract that delivers half the expected savings because volume never reaches it.
"We hit the price. We missed the volume."CFO / Finance Leader
Sees supply cost per patient rising with no clear explanation in the monthly pack.
"Why is supply spend up when volumes are flat?"Clinic or Department Manager
Needs stock today and sees the procurement process as the obstacle.
"I can't wait a week for an approval."AP Manager
Receives invoices without POs and has no contract price to check them against.
"Who ordered this, and is this the right price?"Is off-contract spend happening in your organization?
Tick every statement that is true today. Three or more means the problem is likely costing you real money.
Six root causes behind off-contract buying
Fixing symptoms one supplier at a time does not last. These are the underlying reasons we see most often in clinic and hospital networks.
The contract is invisible at the point of purchase
Negotiated prices sit in a PDF or the GPO portal, not in front of the person placing the order. If the buyer cannot see the contracted item, they buy what they know.
The compliant route is slower than the rep
When raising a request takes days and the rep delivers tomorrow, busy clinical staff choose speed. Every workaround is rational at the site level.
Catalogs are incomplete or out of date
Item masters miss sizes, substitutes or new SKUs, so staff cannot find the contracted product and order a lookalike off contract.
No price check between contract and invoice
Even when the right supplier is used, invoices drift above the agreed price and nobody compares the two before payment.
Nobody sees compliance by site
Without a monthly view of who bought what off contract, there is no feedback loop and no accountability for site managers.
Supplier relationships live with individuals
A long-standing rep relationship with one clinician or manager can outweigh any policy, especially in physician-led practices.
What off-contract spend costs a provider
Off-contract spend is one part of a wider supply chain efficiency gap that published research has measured at scale.
The direct cost is the price premium on each off-contract line. The indirect costs are larger: missed volume tiers and rebates, AP time spent investigating invoices with no PO, and weaker negotiating power at renewal because your data cannot prove the volume you promised.

The expert playbook: six practices that bring spend back on contract
These practices work with any system, including spreadsheets. Order matters: measurement first, catalog second, controls last.
"Most off-contract buying is not people breaking the rules. It is people taking the fastest route to get what a patient needs. If the contracted item takes three clicks and the rep takes one phone call, the rep wins every time. Fix the route, and compliance follows."Md. Kafil, Co-founder and CEO, Zapro. Former senior product specialist on SAP Ariba Network and procurement transformation manager at KPMG.
Measure off-contract spend by site and category
Build a short approved-item catalog at contract prices
Make the compliant path the easiest path
Require a reason code for every exception
Match every invoice to the contract price before payment
Review site compliance monthly and act on outliers
"When I ran a vendor portal for around 15,000 suppliers, the lesson was simple: every document or price that lives in someone's inbox eventually goes wrong. Put the contract price where the order is raised and where the invoice is checked, and most leakage disappears without anyone policing it."Daniel Sagayaraj, Co-founder and CTO, Zapro. Previously built and ran supplier onboarding and payments for a 15,000-supplier marketplace at Voonik.
How Zapro removes the manual work behind contract compliance
Zapro connects the request, the contract, the purchase order and the invoice in one workflow, so the contract price is present at every step instead of living in a separate file.
| Root cause | Zapro capability | What changes |
|---|---|---|
| Contract invisible at purchase | Procurement: catalog requests and "Prompt to buy" with Z1 | Staff pick contracted items at contract price, or describe what they need and Z1 drafts the request. |
| Slow compliant route | Approval workflows with role-based rules | Low-value catalog items move straight through. Exceptions go to the right approver automatically. |
| Supplier and contract data scattered | Contract Management and Vendor Management | One repository for contracts, pricing terms and renewal alerts, linked to a clean supplier profile. |
| No invoice price check | AP Automation with PO and receipt matching | Invoices are captured and matched to POs and receipts, so price and quantity differences are flagged before payment. |
| No compliance view by site | Spend Analytics | Spend by supplier, category and location in one dashboard, so off-contract patterns surface early. |
| Stock and expiry pressure drives rush buys | Inventory Management | Stock levels across locations with low-stock alerts, and transfers between sites before anyone buys off contract. |
Zapro also connects to your ERP or accounting system through API or SFTP, so contracted pricing, suppliers and payment status stay in sync. See Zapro integrations and Zapro for Healthcare.

What a Zapro customer saw after moving this work into one workflow
"Zapro made procurement effortless with a user-friendly interface and stellar support. Our team and suppliers adapted quickly, and we're now seeing faster approvals and smoother collaboration."Maria Rowan, Business Controller, Repromed
Why Zapro for this challenge
Off-contract spend is a routing problem more than a discipline problem. Zapro fixes the route: the contracted item is the easiest thing to order, every exception is recorded, and every invoice is checked against what you agreed to pay.
Built around the vendor, not only the buyer
Contracts, supplier profiles, POs and invoices sit in one record, so pricing is consistent from request to payment.
Z1 does the chasing
Zapro's AI layer reads requests, matches invoices and flags risk, so procurement spends time on suppliers instead of spreadsheets.
Made for multi-site networks
Location-level approvals, inventory and spend views give each site manager their own numbers.
Priced for growing providers
Plans start at $699 per month with unlimited users, so every clinic can use the compliant route.
When Zapro may not be the right fit
- You are a single-site practice buying from one or two distributors. A distributor portal and a monthly invoice review may be enough.
- Your GPO or distributor already enforces formulary buying end to end and your leakage is minimal.
- You need a full clinical inventory system with implant tracking at the point of use. Zapro handles procurement, contracts, AP and stock levels, and works alongside dedicated clinical systems.
Frequently asked questions
What is off-contract spend in healthcare?
Off-contract spend is any purchase of supplies, drugs or services made outside an agreement your organization or its group purchasing organization (GPO) has already negotiated, or bought at a price higher than the contract price. It usually shows up as clinic-level reorders from a preferred rep, emergency buys, or items that were never loaded into a catalog.
How much off-contract spend is normal?
There is no single industry standard, and published benchmarks vary by care setting and category. Most supply chain teams set an internal target for contract compliance and track it monthly by site and category. The useful number is your own trend: if off-contract spend is not falling quarter over quarter, the controls are not working.
Is off-contract spend always bad?
No. Clinical need, a backorder or a better product can justify buying off contract. The problem is unmanaged off-contract spend: purchases nobody reviewed, with no reason recorded, that quietly erode the discounts and rebate tiers you negotiated.
Who should own contract compliance in a clinic network?
Procurement should own the policy, the catalog and the reporting. Finance owns the budget consequences. Clinic or department managers own the buying behavior at their site. Compliance improves fastest when each site manager sees their own compliance rate every month.
Can we fix this without new software?
Partly. A short approved-item list, a written exception rule and a monthly compliance report built from invoice data will reduce the worst leakage. Software becomes worth it when you have several sites, hundreds of items, or AP teams manually checking invoice prices against contracts.
