How to choose an ERP for your building materials warehouse: 10 practical keys

Changing ERP is one of the most expensive decisions any business can make, and at the same time one of the hardest to undo: the cost is not just in the licence, it is in your team’s time, the data you migrate and the mistakes of the first few months. Choose badly and in three years you will be evaluating alternatives all over again. This guide brings together 10 keys that we apply in every ERP Jobers implementation in warehouses and distributors in the building materials sector.

1. Define your critical operations before you look at software

Before you ask for demos, write down on a single page which processes can never fail. For a typical building materials warehouse:

• Receiving purchases and booking them into stock.
• Direct sales to trade customers with their price list and rebate.
• Outgoing delivery note, transport and signature.
• Error-free VeriFactu invoicing.
• Collections and receivables tracking.
• Annual physical stocktake without stopping the business.

Take that list to every demo and ask them to show you each workflow in their system, with no slides. If a supplier only shows presentations, be careful.

2. Real specialisation, not just “we serve the sector”

Any ERP will claim to work for building materials if you pay for it. The questions that filter them out:

• How many active customers do they have in the building materials and ceramics sector? Ask for a specific figure.
• How do they handle shades and calibres in ceramics? If the answer is “with custom fields”, they are not specialised.
• How do they apply a quarterly volume rebate combined with a one-off discount? If the answer is “we configure it bespoke”, not specialised either.
• Can they show you a real customer’s dashboard (with anonymised data)?

3. VeriFactu compliance, already certified

VeriFactu, Spain’s mandatory invoicing-software regulation, comes into force on 1 January 2027 for companies and on 1 July 2027 for the self-employed. Any serious ERP in 2026 should already have the module certified and running, not on a roadmap.

Check that the system:

• Electronically signs every invoice with hash chaining.
• Generates the QR stamp on the document.
• Allows optional real-time submission to the AEAT (the Spanish tax agency).
• Automatically turns any later modification into a corrective invoice.
• Keeps the signed invoices for at least 4 years.

4. Multi-company and multi-warehouse from the start

If you have (or plan to have) more than one warehouse, a regional branch or several legal entities, do not accept an ERP that needs to be “configured later”. Multi-company and multi-warehouse have to be in the core, not bolted on.

Specific tests:

• Create a transfer note between two warehouses and watch the stock move in real time.
• Raise an invoice from company A with customers and items shared with company B.
• Produce a consolidated balance sheet for both companies.

5. Price lists, discounts and rebates: the acid test

This is the most visible difference between a specialised ERP and a generic one. Ask them to set up, live:

• A customer with a special price list on the “wall tiles” range.
• On top of that, a 5% discount on the “porcelain” range for the current month.
• On top of that, a cumulative 3% rebate on the whole quarter’s turnover, applied retrospectively.

A serious sector ERP sets that up in 5 minutes. A generic one tells you “we’ll customise it during implementation”.

6. Integration with the rest of your company’s software

The ERP is the core, but it does not live alone. Ask how it integrates with:

• Sales CRM (visits, pipeline, maps, AI). → JobCRM.
• Delivery and routes (GPS, digital signature on the delivery note). → JobRutas.
• B2B portal so your trade customers can see their account and order online. → JobStocks.
• AI digitisation of invoices and delivery notes. → JobIADoc.
• Time and attendance for warehouse staff. → JobFichador.

If your candidate is ERP only, and for everything else you have to buy other suppliers’ products and connect them via API, having a suite that is integrated from the start saves years of headaches.

7. A support team that knows the sector

Support matters more than the feature list. Before you sign:

• Ask for the response SLA in writing.
• Ask how many people work in support and what time it closes.
• Talk to the head of support, not just the sales rep.
• Ask for 2 phone references from customers similar to you, and call them.

8. What the migration from your current system will look like

A well-executed migration is what separates a successful project from a disaster. Check:

• Which data migrates: items, customers, suppliers, balances, receivables, stock.
• Whether or not there is a period of running in parallel.
• How many weeks the implementation will take, day by day.
• What happens if in month 3 you find something that does not work.

We regularly migrate customers from Sage 200, A3, Ekon, Navision and older sector-specific ERPs. For standard warehouses it usually takes 4–8 weeks; multi-warehouse with a complex migration, 2–4 months.

9. Real total cost (not just the licence)

Compare on 3-year TCO, not the monthly fee:

• Licence (monthly or annual).
• Initial implementation (consultancy days).
• Data migration.
• Team training.
• Ongoing support.
• Cost of customisations (key point: if you need 6 bespoke developments, the “cheap” ERP becomes expensive).
• Hardware or cloud, depending on the model.

A specialised ERP usually has a lower TCO than a customised generic one, precisely because you save on the customisations.

10. A demo with your own data before you sign

If you have reached the end of the process, insist on a demo with your own data (at least your catalogue and customer/supplier master data loaded). It is the only way to see how the system behaves with your real volume, not with the pretty dataset from the presentation.

Common mistakes in the buying decision

• Choosing on a low licence price without looking at TCO.
• Buying a generic ERP and promising yourself “we’ll customise it as we go”. It ends up never-ending.
• Not involving the admin team from the start. They are the ones who will use it 8 hours a day.
• Leaving the migration for “later”. The longer you wait, the more data there is to migrate and the more complicated it gets.
• Not asking for phone references. A 10-minute call to an active customer says more than 50 pages of brochure.

Conclusion

Choosing your ERP well means deciding which company you are going to work with for the next 5–10 years. Specialisation in the building materials and ceramics sector, VeriFactu compliance built in from the start, integration with the operational suite and a support team that knows the day-to-day are the four legs that make the decision sustainable in the long run.
