How do I choose between a procurement suite, a marketplace and a spend analytics tool?
Start from the job you actually do badly today, because the nine tools here are not one product type. Esker, Basware, Mercanis and Planergy run the transaction: someone asks for something, a budget is checked, an approver says yes and a purchase order goes out. Unite does the buying itself from catalogues. Kodiak Hub and SupplyOn manage the supplier relationship and its risks. Sievo does none of these and instead reads the data other systems produce.
A company whose problem is uncontrolled requests usually wants the first group. Esker describes policy-driven approvals with budget checks and web or mobile approval, and tracking of committed spend before invoices arrive. Planergy describes real-time budget tracking that supports approval decisions from a phone. A company whose problem is tail spend on office supplies, tools and consumables is better served by Unite's cross-catalogue search than by a full suite it will never configure.
If you already have an ERP with a requisition module and want to know where the money went, Sievo is the tool that fits, but it is explicitly an analytics layer used next to a requisition or sourcing tool. Buying it as your only procurement system leaves purchase requests unsolved.
How is European procurement software priced, and can I compare it before a demo?
Mostly you cannot. Esker, Mercanis, Unite, Planergy, Kodiak Hub, SupplyOn and Sievo publish no price and route buyers to a demo or a quote. Basware states a subscription model where you choose modules, from invoice automation to eProcurement, and shows no amounts. Spendesk describes a platform subscription plus per-user pricing, quoted by company size rather than published as a single rate.
That makes the pricing question one of structure rather than numbers. Ask each vendor what is the billing unit (users, modules, invoice or document volume, spend under management), what is charged separately (supplier onboarding, catalogue connections, integrations) and what happens at renewal. Basware's module model means the eProcurement price depends on which other modules you buy. Unite's single creditor model is the opposite: the cost sits partly in the catalogue prices and in payment terms that Unite sets.
Two practical habits help. Run the same twelve-month purchase volume past every vendor so the quotes are comparable, and ask for the implementation estimate in the same document, since the heavier suites also carry configuration work that the licence figure hides.
Does a European procurement vendor keep my supplier data under EU jurisdiction?
It improves your position, but each vendor needs checking one by one. The contracting entity is the first test. Mercanis is operated by CdC3 GmbH in Berlin with German law and Berlin as the place of jurisdiction.
Planergy names PLANERGY Ltd in Dublin and applies Irish law. Esker's terms name Esker S.A. in Villeurbanne, but the group also operates in the United States and applies Wisconsin law to visitors there, so the order form should name the European entity. Unite's imprint differs by country, and the UK site names Unite Procurement UK Ltd.
Hosting is the second test and the pages are uneven. Basware's general terms say cloud services for EEA customers are hosted within the EEA, while listing sub-processors in India, the USA and Australia with access for operation, development and support under standard contractual clauses.
Unite says it is hosted within the EU, per its about page. Esker, Mercanis, Planergy, SupplyOn and Sievo do not state a hosting location on the pages we reviewed, and Mercanis's privacy policy mentions providers in the EU and the USA.
So ask three things before signing: which entity is the controller, where the production data sits, and who outside the EU can reach it for support. Sievo shows why the third question matters, since Sievo Oy is the parent of Sievo, Inc., a US subsidiary, even though its privacy policy treats the Finnish company as controller.
How do I move away from Coupa or SAP Ariba without losing my approval history?
Treat it as two migrations, because the live process and the historical record move differently.
Esker, Basware and Mercanis are listed on this site as alternatives to Coupa and SAP Ariba, and Mercanis is also listed against Jaggaer, but they cover the process in different depths: Esker leans on the link to accounts payable, Basware on invoices and a marketplace, Mercanis on intake, sourcing and contracts. Compare module depth for your own flows in a demo rather than relying on the label.
Move the process first and archive the history rather than importing all of it. Open purchase orders and active supplier master data are what the new tool needs on day one. Closed approvals from years ago can stay in an export, which keeps the migration short and keeps the new tool's data clean.
Plan the supplier side too. Suppliers who send acknowledgements and invoices through your old portal have to be moved, and a network tool like SupplyOn only helps if your suppliers already sit on it. SupplyOn lists more than 140,000 companies, so for an automotive buyer the migration may be lighter than the generic advice suggests.
When should I not switch to a European procurement tool?
Switch only if the replacement covers what you use. Unite does not replace a sourcing, contract or supplier-qualification suite, because it covers catalogue-based indirect purchasing. Sievo does not run purchase requests, purchase orders or supplier onboarding. Kodiak Hub is broader than a team needing only risk management and could mean paying for workflow it does not use. Planergy is described for mid-market firms, so a large enterprise with complex sourcing may find it light.
Do not switch either if the driver is only ideology. A company whose legal team needs a European contract and a European regulator gets that from most of the vendors here. A company that needs no American entity anywhere in the chain will find that none of the pages we reviewed make that promise, and several name US subsidiaries or sub-processors.
Timing matters too. A procurement tool touches every department, so replacing it in the middle of a year-end close or an ERP project adds risk without adding value. A smaller step is often better: add Sievo for analytics, or Unite for catalogue buying, and leave the transactional core where it is until the contract ends.
How should a procurement tool connect to the ERP and the accounts payable process?
The integration test is whether purchase orders and invoices end up matched without retyping.
Esker and Basware are the two tools here where procurement and accounts payable are the same vendor: Esker says procurement and finance share the same data, and Basware lists AP automation, invoice matching and an e-invoicing network next to eProcurement. Planergy offers procure-to-pay and AP automation together, and says integration with an existing ERP and accounting tools can be done in days, which is a company claim worth testing with your own system.
For catalogue buying, Unite connects through punchout OCI, cXML and an API, according to the vendor, or can be used on its own through the web interface. Planergy lists 32-plus punchouts including Amazon Business, Staples and Grainger. Punchout lets an employee shop in a supplier's catalogue from inside your approval flow, so budgets and approvals still apply.
Spendesk sits slightly apart: it captures supplier invoices, issues cards and exports to the common European ledgers, so its integration question is about your accounting package rather than your ERP purchasing module. Ask each vendor for the list of ERPs it has connected in production, not the ones on the roadmap.
