ERP gap apps for growing businesses

Rapid apps that close your ERP gaps.

Your ERP runs the core of the business. We build the focused, affordable apps that handle what it doesn't — designed by people who have spent their careers implementing and supporting ERP systems.

The gap

Every ERP leaves gaps. Growing businesses feel them first.

As you grow, the processes that sit just outside your ERP multiply. They end up in spreadsheets, inboxes and people's heads — slow, error-prone and hard to scale.

Spreadsheet workarounds

Critical data lives in files that only one person understands.

Re-keying between systems

The same order, job or invoice is typed in two or three times.

Paper on the shop floor

Warehouse, field and site teams can't easily reach the ERP.

Costly customisation quotes

Changing the core ERP is expensive and makes upgrades harder.

Services

Focused apps, built around your ERP

Each app solves one clearly defined problem, connects to the systems you already use, and is scoped and priced before we start.

Workflow and approval apps

Purchase approvals, quality checks, returns, onboarding — structured processes with an audit trail, written back to your ERP.

Mobile and field apps

Goods-in, stock counts, proof of delivery, site timesheets. Simple, phone-friendly apps for people who aren't at a desk.

Integrations and connectors

Link your ERP to e-commerce, CRM, carriers, banks and spreadsheets so data moves once, accurately, without re-keying.

Customer and supplier portals

Let customers check orders and invoices, or suppliers confirm deliveries, without phoning your team.

Reporting and dashboards

Live views of the numbers that matter, combining ERP data with the information it doesn't hold.

Automation

Scheduled jobs, alerts and document generation that remove repetitive manual steps from your week.

ERP advisory and support

Not sure whether the answer is configuration, an app or a different process? We bring ERP systems design, implementation and support experience to help you decide — before anything is built.

Concept designs for the kind of apps we build around Unleashed, Xero, Sage, Shopify and other systems.

Mobile app

Goods-in at the dock

Deliveries were checked against paper purchase orders, then re-keyed into Unleashed at the end of the day. Discrepancies surfaced days later.

UnleashedWeb app

Shopify to Sage order hub

Online orders from Shopify were copied into Sage by hand each morning. Stock shortfalls and pricing errors were found after customers had paid.

ShopifySageMobile app

Purchase approvals on the go

Purchase requests were approved through long email chains. Budget holders couldn't see what was already committed, and nothing was recorded consistently.

Xero

Why Appscelerate

ERP expertise first. Apps second.

Most app builders learn your ERP on the job. We start from a deep understanding of how ERP systems are designed, implemented and supported — so the apps we build fit properly and last.

We speak ERP

Data models, posting logic, permissions and upgrade cycles. We understand what your ERP does well and where it stops.

Rapid, scoped delivery

Small, well-defined apps delivered in short iterations, with working software to review at each stage.

Affordable by design

A focused app usually costs a fraction of a core ERP customisation, with a clear price agreed before work begins.

Upgrade-safe

Apps sit alongside your ERP and connect through supported interfaces, keeping your core system clean.

FAQ

Questions we’re often asked

What is an ERP gap?

Any part of your operation that your ERP doesn't handle well — a process kept in spreadsheets, a team that can't access the system, or data that has to be typed in twice. Most businesses have several.

Do you change our ERP system?

Usually not. We build apps that sit alongside your ERP and connect through its supported APIs and integration tools, which keeps your core system easier to upgrade and support.

How quickly can an app be delivered?

It depends on the scope, which we agree with you before starting. Focused apps are typically delivered in weeks rather than months, and you'll see working software early.

How much does it cost?

Each app is scoped and priced individually, and you receive a clear quote before any work begins. Our aim is to be a fraction of the cost of a core ERP customisation.

Who owns the app and the data?

Your data stays yours. Ownership, hosting and support arrangements for each app are set out clearly in your agreement.

Can you help if we haven't chosen an ERP yet, or our implementation is struggling?

Yes. Our background is ERP systems design, implementation and support, so we can advise on selection, recovery and optimisation as well as building apps.
