The best supplier relationship management (SRM) software for an SME keeps every supplier, document, contract and score in one place without an enterprise price or a long rollout. oboloo has a free-forever plan with unlimited suppliers and users, and adds onboarding, compliance and scorecards in Supplier Plus at $28 per user a month. Gatekeeper and Kodiak Hub are dedicated SRM platforms for growing and mid-sized teams, sold by quote. If you mainly need purchase orders and invoice approval, Tradogram, Precoro and Zapro are purchasing tools that include supplier management. The benefits of supplier relationship management software for a small business are simple: fewer spreadsheets, no expired certificates, and a clear view of which suppliers perform.

Supplier management (also called vendor management) software gives each supplier one record. For an SME, that usually covers five jobs:
See our supplier management software page for how this works in oboloo.
Purchase-to-pay (P2P) tools handle requisitions, purchase orders, receiving and invoices. Many include a supplier list or portal, but the supplier side exists to support the order and the payment. SRM tools start from the supplier: who they are, whether their documents are current, how they perform and what you have signed with them. If your pain is chasing approvals and matching invoices, buy a P2P tool. If your pain is not knowing which suppliers are compliant or performing, buy SRM.
oboloo is free-forever procurement software for SMEs and charities. The free plan includes the core supplier management module with unlimited suppliers and unlimited users, plus contract management, sourcing and savings tracking. Supplier Plus, at $28 per user a month billed annually, adds supplier compliance, onboarding, document requests from suppliers, custom fields and tabs, and supplier scorecards. Scorecards use your own weighted criteria, suppliers can complete them with internal review before anything counts, and scores are tracked over time. Each contract links to its supplier, sourcing activity and savings. There is a 14-day free trial, and registered charities get 50% off paid plans, forever.
Where it fits less well: oboloo does not do purchase orders or invoices. If you need those, pick a P2P tool.
Gatekeeper sells three plans by quote: Pro ("for growing teams", up to 250 third parties), Enterprise (up to 750) and Enterprise Plus. Every plan includes a vendor portal, risk register, unlimited contracts and unlimited users. Balanced scorecards are only in Enterprise and above. Prices are not published.
Kodiak Hub is a dedicated SRM platform covering supplier onboarding, risk and compliance checks, performance scorecards and ESG reporting for rules such as CSRD and the Modern Slavery Act. Its own comparison describes it as best for "mid- to enterprise businesses". Prices are not published; you book a demo.
Tradogram is a purchasing platform. Its supplier management covers a vendor self-service portal, vendor records with certifications and compliance documents, and weighted vendor scorecards. Essentials costs $99 a month billed monthly, or $950.40 a year billed annually, with extra users charged on top (fee not published). If you need purchase orders and invoice approval, Tradogram is built for that; oboloo is not.
Precoro is a procurement and AP tool for mid-sized companies. Core starts at $499 a month billed annually and includes vendor management. The supplier portal and vendor onboarding with approvals sit in Automation, from $999 a month billed annually. Precoro's portal lets suppliers upload documents and update catalogues, and it flags expiring certificates. If you need purchase orders and invoice approval, Precoro is built for that; oboloo is not.
Zapro sells intake-to-pay software with vendor onboarding and vendor performance tracking. Spark is $699 a month "for startups and small teams", with up to 50 vendors and unlimited users; Growth is $1,999 a month for up to 500 vendors. Both list "Standard SRM". It also handles purchase requests, purchase orders and invoice matching.
HICX and Graphite Connect are strong supplier data platforms, but both sell to very large organisations: HICX names global brands such as Unilever and Heineken, and Graphite Connect says it is trusted by the Fortune 100. Neither publishes prices. Suites such as SAP Ariba, Coupa, JAGGAER and Ivalua cover SRM inside a full source-to-pay platform. For most SMEs they bring more setup, cost and process than the supplier base needs.
For the detail on each part, see our guides to supplier onboarding software, supplier compliance software and supplier scorecards.
Software that holds one record per supplier, with their documents, compliance status, contracts and performance scores, so you can manage the relationship rather than just the order.
It depends on budget and whether you need purchase orders. oboloo is free forever for supplier management, with paid compliance and scorecards. Gatekeeper and Kodiak Hub suit growing and mid-sized teams buying a dedicated SRM platform by quote. Tradogram and Precoro suit teams that need POs and invoices.
Yes. oboloo's free-forever plan includes supplier management with unlimited suppliers and users. None of the other tools in this list publishes a free plan.
P2P software manages the buying process: requisitions, purchase orders and invoices. SRM software manages the supplier: documents, compliance, scorecards and contracts.
One place for supplier data, reminders before documents expire, consistent performance scores, and contracts linked to the supplier they belong to. For vendor compliance, that means fewer surprises at audit time.
