Where systems meet
A B2B order is more than a checkout. A fulfilment platform is more than a dashboard. Pricing, inventory, finance, carriers and customer journeys all need to agree. We build where those dependencies meet, not around isolated tickets.
01 / COMMERCE OPERATIONS
Orders outgrow manual
checks
At Apex, customer-specific pricing, stock, credit checks and dropship orders had to work together across Shopify Plus and Exact Online. Isolated connections were not enough.
02 / BUSINESS-CRITICAL SOFTWARE
One platform. Many users and processes.
At eFulfilment Europe, warehouse operations, merchant dashboards and shopper portals rely on one system. Changes need to work across all three layers.
03 / ENGINEERING CAPACITY
The roadmap grows faster than the team
Your team must develop new functionality and keep production stable. Hiring takes time; rotating freelancers lose context. Dedicated engineers need to become part of the existing way of working.
Our starting point is the operation behind the request: what must work, who owns it and what a change affects.
What our engineers build
01 / COMMERCE
Shopify Plus & B2B commerce
Company accounts, customer-specific pricing, B2B checkout, partner onboarding and storefront logic. Built around real wholesale processes, as with Apex Power Supplies.
02 / CUSTOM PLATFORMS
Custom software & portals
Merchant dashboards, partner portals, warehouse systems and internal applications. BizzyBee at eFulfilment connects warehouse, merchants and shoppers in one platform.
03 / BACKEND
APIs & ERP integrations
Robust connections between Shopify, Exact Online, payment providers, CRM and carrier systems. We design data contracts, validation, failed states and operational control.
04 / FRONTEND
Websites & digital experiences
Framer, React and modern frontend development for websites, dashboards and customer journeys. Built with performance, accessibility, content architecture and maintainability in mind.
05 / PLATFORM QUALITY
Data, DevOps & quality assurance

06 / ENGINEERING CAPACITY
Dedicated development teams
Frontend, backend, data, DevOps and QA engineers who join your repositories, backlog and sprint structure. You keep the product roadmap; Sandstone coordinates capacity and continuity.
A complete project, a dedicated engineering team or focused specialist capacity. We agree on the right model for your platform and roadmap.
A SANDSTONE SOLUTION / B2B ORDER AUTOMATION

DEDICATED REMOTE ENGINEERING
When a roadmap grows faster than the internal team, we do not set up a second delivery organisation. Sandstone engineers join your existing repositories, tools, backlog and sprint structure. You retain product ownership and technical direction; we provide engineering capacity, coordination and continuity.
YOUR ORGANISATION
You set the direction.
✓
Product vision & roadmap
✓
Priorities, backlog & architecture
✓
Technical approval & acceptance
OUR ENGINEERS IN TANGIER
We build inside your team.
✓
Frontend · backend · data · DevOps · QA
✓
Stand-ups, code reviews and sprint delivery
✓
Production experience, documentation & knowledge transfer
ONE INTEGRATED DEVELOPMENT TEAM
One repository
One backlog
One sprint rhythm
One code review standard
Engineers work within the agreed hours on your product only. Sandstone supports onboarding, capacity planning, evaluation and continuity. Without adding a separate project-management layer.
CLIENT PROXIMITY
The Hague
Strategy, client collaboration and the commercial context in Europe.
TECH & AI HUB
Tangier
Engineering, development and AI specialists connected to every region.
CLIENT PROXIMITY
Dubai
Full-service contact and collaboration for clients in the Gulf.
HUMAN ENGINEERING + AI ACCELERATION
Our engineers use approved AI tools to speed up implementation, analysis, tests and documentation. But AI does not know why an architecture exists or what a change might break. The engineer makes the technical decision, validates every output and remains accountable for what ships.
WHERE AI HELPS
Acceleration
Implementation and refactoring
Codebase analysis and debugging
Test preparation and documentation
API work and review preparation
WHAT ENGINEERS SAFEGUARD
Engineering judgment
Architecture and dependencies
Security and approved tooling
Code review, validation and tests
Maintainability, releases and ownership
Approved tools only. No confidential client code or data sent to external AI services without permission. Human review and testing remain mandatory.
Our delivery approach
For development projects, we use the same connected approach as the wider Sandstone team. Technical decisions follow the business problem, and delivery stays accountable across design, code, operations and adoption.
01 / DIAGNOSE
Find the bottleneck.
Map customer and internal workflows, existing applications, data, constraints and the point where value or time is lost.
02 / ALIGN
Agree the architecture.
Align business owners and engineers on priorities, interfaces, responsibilities, technical choices and measurable outcomes.
03 / BUILD
Engineer and validate.
Build in working increments with code review, automated checks, integration tests and clear handling of exceptions.
04 / ACTIVATE
Launch and optimise.
Release carefully, check real workflows and improve from production evidence. Documentation and ownership remain part of delivery.
THREE WAYS TO WORK WITH US
You can ask us to own a defined delivery, expand your existing development team or assemble a complete engineering team. The working model is agreed before anyone starts, including scope, ownership and reporting.
01 / PROJECT
WHEN IT FITS
You have a specific system to build or improve.
02 / TEAM EXTENSION
WHEN IT FITS
Your roadmap is clear, but internal capacity is tight.
03 / DEDICATED TEAM
WHEN IT FITS
You need a stable product team, not separate freelancers.
THE SAME STANDARDS IN EVERY ENGAGEMENT
Senior people doing the work · one dedicated point of contact · clear agreements and reporting · code reviews, tests and documentation · AI within client-approved guardrails.
● COMMON QUESTIONS
Two ways to work with Sandstone: have us build and own a defined solution, or add engineers to your existing team and roadmap. These are the questions that shape the right engagement.
01 / SHOPIFY
Do you develop Shopify and Shopify Plus stores?
Yes. We build B2B and B2C commerce experiences, including company accounts, customer-specific pricing, storefronts and checkout workflows. The solution is designed around your commercial model and Shopify’s available capabilities.
02 / INTEGRATIONS
Can you connect Shopify to Exact Online or another ERP?
Yes. We design and implement API integrations for orders, products, customers, stock and financial workflows. We also define how exceptions, validation and failed synchronisations are handled.
03 / CUSTOM SOFTWARE
Can you build a custom portal or web application?
Yes. We develop partner portals, customer dashboards and internal tools when standard applications do not support an important process. We define the scope and architecture before implementation.
04 / FRAMER
Can you improve an existing website?
Yes. We can improve CMS architecture, component systems, technical SEO, performance, accessibility and conversion journeys without assuming a complete rebuild is necessary.
05 / PROJECT APPROACH
Can Sandstone engineers join our existing development team?
Yes. Our frontend, backend, data, DevOps and QA engineers work within your own repositories, tools, backlog and sprint structure. You retain the roadmap and technical decisions; Sandstone manages coordination and continuity.
06 / ONGOING SUPPORT
How do your engineers use AI without compromising code quality?
AI can accelerate implementation, refactoring, tests and documentation, but it does not replace engineering judgment. We use client-approved tools and keep code review, validation, testing, architecture and security in the hands of accountable engineers.
