No. 01 · Bespoke business software

Custom ERP for businesses that have outgrown the off-the-shelf.

A small, deliberate practice building bespoke operations software for SMBs in the UK and Spain — designed, written and supported by one engineer.

§ 02Practice

Software written for the way you actually work — not the other way around.

  1. ERP Implementation

    Orders, inventory, accounting, customers, ops. One coherent system instead of seven spreadsheets and a CRM nobody updates. Built around the workflows that already make money.

  2. eCommerce Platforms

    Storefronts joined at the hip to the back office. One source of truth for stock, pricing, fulfilment and finance — no nightly sync job pretending to be integration.

  3. Process Design

    Map the operation before writing the code. Find the duplication, surface the right data, remove the friction. Half the work happens before a keyboard is touched.

  4. Data Migration

    Out of spreadsheets, legacy systems, or generic SaaS — without losing history, references or accounting integrity. Reconciled to the cent on day one.

  5. Regulatory Compliance

    UK and Spanish requirements as a baseline, not an afterthought. MTD · SII · VeriFactu · VAT, IVA, IRPF — wired in from the start.

  6. Long-term Support

    A working relationship measured in years, not sprints. New modules, integrations and refinements as the business evolves. The system grows with you.

§ 03Approach

Four stages, in this order. Always.

i · Discover

Sit with the business.

Understand the operations, the people, the constraints. No system design until the picture is clear.

ii · Design

Map before code.

Processes, data models, scope. Agree what gets built first, and what is deliberately deferred.

iii · Build

Iterative, in production.

Modern, maintainable stack. Real software in real use, early and often — never a six-month black box.

iv · Operate

Migrate, train, grow.

Cutover, hand-holding, and a long-term partnership. The system evolves alongside the business.

Off-the-shelf software is a polite assumption that every business is the same. Most aren't.

§ 04Contact

If off-the-shelf hasn't solved it, we should talk.

A short note works better than a long form. Tell me what's broken, what's been tried, and what success would look like.
