Custom management software: ERP and CRM

Cost and timeline
A simple custom ERP/CRM (customer/supplier records, one specific process flow and a basic dashboard) usually starts from €2,500-3,900 and takes 6-10 weeks. Cost goes up with accounting integrations, e-invoicing, syncing with an ERP/CRM you already use, or migrating historical data from spreadsheets.
We recommend starting by replacing whichever process causes the most pain today (a shared spreadsheet that breaks every month, for example) rather than trying to replicate every feature of a commercial ERP/CRM you probably don't fully use anyway.
Common mistakes when migrating from Excel or a generic ERP
The most common one is trying to migrate every process at once instead of starting with whichever one costs the team the most time, which stretches out the project and delays the first visible result. The second is not cleaning the data before migrating (duplicates, inconsistent fields), which just carries the same mess into a new system. The third is not training the team on the new workflow before switching, so people keep using the spreadsheet "just in case" and the new system never gets fully adopted.
Frequently asked questions
Custom ERP or off-the-shelf? If your process is your advantage, custom avoids forcing yourself into rigid software. If it's very standard, integrating may be enough. We assess it with you.
Can you migrate my current data? Yes, we migrate from Excel, Access or other systems with validation and backups.
Does it integrate with my invoicing or accounting? Yes, we integrate with invoicing, accounting and gateways when an API or export exists.
Who can access what? We define roles and permissions by team, location or profile with activity logs.
