Your business isn't standard. Your ERP shouldn't be either.
We implement the Core family of business management software: a complete ERP, accounting, CRM and seven industry-specific programs that already speak the language of your business. We configure them with you, adapt them to the way you work and connect them to your PrestaShop store.
- Our own software, fully customisable
- PrestaShop integration and e-invoicing
- Support from people who know the software inside out
Generic software forces you to work the way it wants
Parallel spreadsheets, data typed in twice, reports nobody trusts enough to open. When the software doesn't understand your industry, your team ends up doing the extra work.
You don't know if you're making money
Every job, campaign or contract has its real cost. An industry ERP shows it to you while you work, not at the end of the year.
Everything gets typed twice
Online store orders, delivery notes, invoices and accounting all connected: what's entered once works everywhere.
Regulations never stop changing
E-invoicing, Verifactu, SILICIE, SEPA direct debits… The software adapts to every legal change without you having to switch providers.
Software that already speaks the language of your business
Seven industry-specific programs built on the same management core. We start from what already works in your industry and fine-tune it for your company.
Installations
CoreMed
For electrical, plumbing, HVAC and security companies: quotes, jobs, job sheets, warehouse, vehicles and staff, with the real cost of every job.
- Job sheets signed on site from a mobile phone

Textile
CoreTex
Textile distribution for wholesalers, store chains and garment makers, with the size and colour matrix across the whole cycle.
- Models, seasons and pre-orders
- Sales agents and commissions
- Multi-warehouse stock and online store
Advertising

Your industry isn't listed?
We build it on the same management core, with an analyst who studies how you work from day one.
CoreGest, CoreConta and CoreCRM: one piece of data, everywhere
The foundation of all the industry programs. A delivery note updates the stock, the invoice generates its accounting entry and its e-invoice, and the payment goes into the SEPA direct debit batch. Without retyping anything.
- CoreGest: ERP for SMEs with sales, purchasing, warehouse, POS, treasury and reports.
- CoreConta: financial and cost accounting, taxes, fixed assets and budgets.
- CoreCRM: customers, opportunities, sales actions and tracking of your sales team.
- Multi-company and multi-warehouse, with access from the office, warehouse or job site and per-user permissions.
If it doesn't exist, we build it
Standard software often can't cover what you need. We start from our management core or develop the application from scratch, with an analyst from the very first meeting and regular deliveries so you can see how it's progressing.
- New modules, reports and integrations whenever you need them
- Data migration from your current software, tested in parallel
- Connection with your PrestaShop store, banks and the Spanish Tax Agency (AEAT)
- Living software: it evolves with your company

Comply with the law without changing the way you work
E-invoicing
Spanish e-invoicing mandate between businesses: October 2027 if your turnover exceeds €8M and October 2028 for everyone else (RD 238/2026).
Verifactu
Chained invoicing records, QR code and submission to the AEAT. The Spanish Tax Agency has announced its postponement to 2028.
SILICIE
Excise duty entries sent to the AEAT straight from your own warehouse movements.
SEPA direct debits
Collections and payments in SEPA format, with returns tracked for the next batch.

What people ask us about custom ERP
Is it standard or custom software?
Both. We start from proven programs (CoreGest, CoreConta, CoreMed…) and configure and adapt them to your company. If what you need doesn't exist, we build it. You get the reliability of a product and the fit of an in-house development.
Does it connect to my PrestaShop store?
Yes. Orders, customers, stock and prices are synchronised between your store and the ERP, and invoicing comes out of the ERP meeting all legal requirements. It's explained on the CoreGest integrated with PrestaShop page.
Can I bring over my data from the software I use now?
Yes. We migrate customers, suppliers, products, outstanding receivables and payables and, where possible, history and accounting. Before the final switch we validate everything with you.
Can I work outside the office?
Yes. You can access it from any device with an internet connection, including tablets on site or in the warehouse, with per-user permissions.
How much does it cost?
It depends on the modules, the number of users and the adaptations you need. After an initial conversation we send you a fixed, written proposal, with no obligation.
