Cloud Based Inventory Systems: Off-the-Shelf or Custom?

How to choose a cloud based inventory system when your current stock process runs in Excel, including when standard software fits and when a managed custom app is better.

By Spreadsheet Upgrade 5 min read Published 15 Aug 2026

If your inventory process currently runs in Excel, moving to a cloud system can solve several problems at once: shared access, live stock records, permissions, mobile use and reporting.

The harder question is which type of system you need.

For many businesses, an established inventory product is the correct answer.

For others, the spreadsheet has evolved around a process that standard inventory software does not fit cleanly. That is where a managed custom application becomes worth considering.

Interactive example

From stock spreadsheet to a live inventory and asset control system

A hands-on demonstration of replacing stock and asset spreadsheets with a browser-based control system for balances, locations, movements, exceptions and reorder attention.

  • Live stock and asset dashboard by location and status
  • Receipt, issue, transfer and count-style workflow stages
  • Low-stock and exception visibility without editing formulas

Demonstration only. Sample data stays separate from any real customer system.

Start with the workflow your spreadsheet is handling

Before comparing software, list what the workbook actually does.

It may cover:

  • stock on hand;
  • receipts;
  • issues;
  • transfers;
  • reservations;
  • reorder points;
  • batch or serial information;
  • purchasing;
  • job allocation;
  • adjustments;
  • inspections;
  • reporting.

Then list the work that happens outside it.

For example:

  • warehouse staff message someone to confirm a transfer;
  • purchasing receives reorder requests by email;
  • finance gets a separate export;
  • managers manually approve stock adjustments;
  • site staff cannot update the workbook from a phone;
  • someone rebuilds the monthly stock report.

Those surrounding steps often determine whether standard software will fit.

When off-the-shelf inventory software is the better choice

Choose a standard product when your needs are close to common inventory patterns.

That is especially true when you want familiar capabilities such as:

  • receipts and issues;
  • purchase orders;
  • stock locations;
  • reorder levels;
  • barcode support;
  • standard stock reports;
  • common accounting integrations.

Buying a mature product can be faster and cheaper than specifying a custom system.

Do not commission bespoke software merely to recreate features that already exist in well-supported inventory platforms.

When the spreadsheet is hiding a more specific process

Custom becomes more relevant when stock is only one part of a wider workflow.

Examples include:

Stock tied to jobs

Materials may need to be reserved against jobs, issued in stages and reconciled against job completion.

Production-specific rules

Availability may depend on work-in-progress, planned production or unusual units and conversions.

Approval-heavy stock movements

Adjustments, write-offs or high-value issues may require specific approval paths.

Equipment or asset workflows

The business may need check-in, check-out, inspection, service and location history rather than conventional stock control.

Customer-specific operations

Inventory may be held, allocated or reported differently for particular contracts.

Existing systems create gaps

The business may already have accounting or ERP software, while one awkward operational process remains in Excel because the standard system does not handle it well.

These are the situations where a focused managed app can be more appropriate than replacing the entire technology stack.

Questions to ask any cloud inventory provider

Whether you buy standard software or commission a custom app, check:

  • Can several people work at the same time?
  • Are records updated centrally?
  • Can users have different permissions?
  • Is there a clear history of important changes?
  • Can staff use it on phones or tablets?
  • How are stock adjustments controlled?
  • Can data be exported?
  • How are backups handled?
  • What happens when users leave?
  • Can the system integrate with the tools you already use?
  • Who supports it after launch?

The answers matter more than the number of features on the product page.

Excel inventory warning signs

An Excel stock process is worth reviewing when:

  • several copies are circulating;
  • users overwrite formulas;
  • staff re-enter data into other systems;
  • stock locations are regularly out of date;
  • reporting takes significant manual time;
  • only one person understands the workbook;
  • users need mobile access;
  • approval steps happen outside the file;
  • errors affect purchasing, production or customer delivery.

One user can still justify an upgrade if the repetitive administration is large enough. The decision should be based on process cost and control, not headcount alone.

Use the spreadsheet cost calculator if you want to estimate the staff time involved.

What a custom inventory app can look like

A focused application might provide:

Receive stock → allocate → issue → transfer → adjust → report

with:

  • validated forms;
  • live quantities;
  • role-based access;
  • approval rules;
  • job or project links;
  • documents;
  • audit history;
  • dashboards;
  • mobile-friendly screens.

The objective is not to build a generic warehouse-management platform.

It is to replace the specific spreadsheet-led process that is creating friction.

Where Spreadsheet Upgrade fits

Spreadsheet Upgrade is not an off-the-shelf inventory package.

It is relevant when your current inventory or stock-control process already works in principle but has become awkward, fragile or difficult to share because it lives in Excel.

The first step is the free fit check.

If the workflow looks suitable, the standard Spreadsheet Assessment is £295 excluding VAT in the selected currency. That assessment defines the replacement scope before a managed app is recommended.

For eligible managed plans, the agreed first build is included subject to the published terms, with hosting, backups, maintenance, security fixes and support handled as part of the service.

If a standard inventory package clearly fits your needs, use it. If your spreadsheet exists because your workflow does not fit standard software cleanly, start with the free fit check.

Ready to look at your own process?

Start with a £295 Spreadsheet Assessment

We review the spreadsheet and the work around it, then define what should stay in Excel, what should change and what a sensible first app release would include.

Book the assessment

A human development team is included

You bring the workflow. We handle the software.

Your plan includes people who learn how your business works, design and build the app, check the important details and support it after launch. You are not left to configure a builder or make technical decisions alone.

You are buying a finished app, not a software-building tool

We agree the calculations, access, wording and workflow with you, then take responsibility for turning that into working software.

Human-led delivery Custom to your workflow Support after launch

Your development team

We turn your spreadsheet process into a real app. You explain the work; we handle the design, build and technical choices.

Built around the real process

Screens, calculations, approvals and terminology are shaped around how your business actually works, not forced into a generic template.

Checked before people rely on it

Important rules, access and workflows are reviewed with you and tested before launch instead of assuming a generated first pass is correct.

The same team stays with you

Managed plans include hosting, backups, maintenance, security fixes and ongoing support from people who understand the app they built.

Your spreadsheet, your workflow

Get a clear plan before committing to a build

The £295 Spreadsheet Assessment is the planning step. We review how the file is used, the people and hand-offs around it, the important rules and data, and the practical options for replacing or improving the process.

If you go ahead with a build, the full assessment price is credited before VAT.
