Vendor PortalDevelopment
A supplier-facing portal where vendors register, receive purchase orders, submit invoices and check payment status without chasing your accounts team.
Vendor Portal Development: what the work involves
Buying organisations lose time to paperwork with suppliers. Vendors email invoices to several people, ask when they will be paid, and send expired registration documents that nobody notices. Procurement keeps one list, accounts another, and an invoice approved in one department is unknown in the other. A vendor portal gives suppliers one place to deal with you and gives your team structured data instead of attachments.
DevKey builds vendor portals on top of your procurement and payables process. A supplier completes onboarding with documents that your team reviews and approves, then receives purchase orders, confirms them, and submits invoices against matching orders. Your staff see invoices in a three-way matching queue, and vendors see approval and payment status. Reminders flag documents about to expire, and everything is logged.
Core features
Supplier onboarding and approval
Vendors register, upload registration and tax documents and bank details, and your team reviews them before the supplier is activated.
Purchase order exchange
Issue orders to vendors through the portal, let them acknowledge or propose changes, and keep a record of agreed quantities and dates.
Invoice submission and matching
Vendors submit invoices against an order, and the system checks them against the order and goods received before approval.
Payment status visibility
Suppliers see whether an invoice is received, approved, scheduled or paid, which ends repeated status calls to accounts.
Compliance document expiry
Licences, tax registrations and insurance certificates carry expiry dates, with reminders to the vendor and a flag to procurement.
Performance notes
Record delivery timeliness and quality issues per vendor, supporting reviews and future sourcing decisions.
What we get right before launch
Bank detail fraud
Changed bank details are a common route for fraud. We require a second approver and an out-of-band confirmation step before any payment account is changed.
Linking to your ERP or accounts
Orders and payments originate elsewhere. We scope the integration to your current system, using its API or a scheduled exchange, rather than assuming a standard one.
Vendors of mixed digital skill
Some suppliers are small shops with limited IT. We keep forms short, accept PDF and photo uploads, and provide a simple help guide to reduce support calls.

Common questions, answered
Can vendors upload invoices directly?
Yes. They select a purchase order, enter or upload the invoice and submit it. The portal checks totals against the order and routes it to the right approver, so accounts stop retyping emailed PDFs.
How do you vet new suppliers?
Onboarding collects the documents you require, and a reviewer approves or rejects with a comment before the vendor can transact. The process and checklist are yours to define, and every decision is logged.
Can it connect to our accounting system?
Usually, if the system has an API or accepts file imports. We confirm what yours supports early, then exchange vendor records, orders and payment status so data is entered once rather than twice.
Does it work for service contractors as well as goods suppliers?
Yes. Instead of goods receipt, an invoice can be matched to a work order, milestone or timesheet approved by your project owner, which suits subcontractors and consultants.
