01
The software dictates the process
The team bends its work to the software's limits and keeps the exceptions outside the system.
Custom ERP
A custom ERP to run your company the way it actually works
When daily operations are split between software that does not fit, spreadsheets and processes only two people understand, we build a custom ERP: your own management system, built module by module around how your team works, not the other way round.
Off-the-shelf ERP, customise or build: what to compare
Swipe to compare all options
| Criterion | Off-the-shelf ERP | Customise an existing one | Custom ERP |
|---|---|---|---|
| Process fit | Common industry processes and available configuration. | Partial fit; exceptions depend on extensions. | Rules, workflows and screens defined for your operations. |
| Getting started | Configure, load data and train the team. | Review limits, build extensions and test upgrades. | First module in use, then growth in stages. |
| Recurring costs | Licences per user or module. | Licences plus maintenance of the customisations. | Hosting, support and evolution as per the proposal. |
| Dependency | The vendor's roadmap and terms. | Vendor and compatibility of each customisation. | Technologies, providers and contract terms. |
| Evolution | Whatever the product includes. | Limited by what the product allows. | New modules when the business needs them. |
Key decisions
What to review first
Migrating data without stopping the business
01We inventory the current software and spreadsheets, clean duplicates and agree the field mapping. We test the migration on a copy, the team validates items, customers and balances, and we plan the switch for a quiet period, with a rollback plan.
Connected to what already works
02A custom ERP does not have to do everything. If accounting, the online shop or the CRM work well, we connect them instead of replacing them and define which system owns each piece of data.
What we need to prepare a proposal
03Processes and exceptions, users and roles, approximate volume of orders, items and documents, current systems and required integrations. The scope documents what each stage includes and how it is accepted. Ownership, hosting, third-party licences and maintenance are defined in the proposal and contract.
Problem
Signs your operations need their own ERP
The value is making the friction visible: where the flow breaks, what it costs and what should be automated first.
02
Excel as a parallel system
Stock, planning or costs are calculated in spreadsheets updated by hand that nobody dares to touch.
03
Figures that do not match
Orders, warehouse and invoicing show different numbers, and closing the month means checking everything by hand.
Visible cost
Before you decide
A custom ERP is not always the answer. If an off-the-shelf ERP covers your operations with reasonable configuration, we will tell you. Building pays off when your processes are part of your edge or when adapting a product costs more than building what you need.
How SareLogic can help
A management system built module by module
We start with the process that hurts most, usually orders, inventory or production, and put it to work with real data. Then we add modules by priority. The team uses the system within weeks and the scope adjusts as we learn.
Common cases
Common modules, depending on the agreed scope
Orders, purchasing and inventory
Order entry, stock reservations, receipts, locations and reorder alerts that follow your business rules.
Production and operations
Work orders, planning, timesheets, batch traceability and time and cost control.
Invoicing, reports and connections
Delivery notes, invoicing, dashboards and connections with accounting, CRM, online shop or banks after reviewing their interfaces.
Process
From your operations to the ERP your team needs
Process map
01We walk through orders, warehouse, production and invoicing with the people who do them every day.
First module
02We pick the process with the most impact and agree functions, data and acceptance criteria.
Development with demos
03We show progress every few weeks and test with real data before going live.
Growth in stages
04We add modules, integrations and reports by priority, with agreed documentation and support.
A verifiable scope
- Documented map of processes, roles and data.
- Modules built with the functions agreed for each stage.
- Data migration tested and validated by the team.
- Integrations with the systems you keep.
- Usage, operation and continuity documentation.
How we approach an ERP
- We compare configuring an off-the-shelf ERP, adapting it or building before proposing anything.
- Every module answers a specific process and the people who use it.
- We deliver in stages so the system is used early and risk stays low.
- We document code and decisions; ownership and terms are set in the contract.
Frequently asked questions
Questions before contacting us
How much does a custom ERP cost?
It depends on modules, users, integrations and the data to migrate. That is why we start with one priority module: it shows the real cost with a limited scope before committing to the whole system.
How long until it is up and running?
A first module is usually in use within a few months, depending on its scope. The rest grows in stages while the team already works with the system.
Can we migrate from our current software or from Excel?
Yes, after reviewing what data exists, its quality and how it can be exported. We test on a copy and the team validates the information before the switch.
Does it connect with our accounting or online shop?
It depends on their interfaces, permissions and terms. We review what is synchronised, which system owns the data and how errors are handled before committing to the integration.
