A missing gasket during a Saint John refinery turnaround costs more than your whole inventory system

Custom inventory software in Saint John runs CAD $40k to $120k over 3 to 6 months. The payoff is knowing every critical spare and MRO part is in stock before a turnaround, not discovering the gap when a crew is standing idle.

The short answer

Custom inventory software in Saint John runs CAD $40k to $120k over 3 to 6 months. The payoff is knowing every critical spare and MRO part is in stock before a turnaround, not discovering the gap when a crew is standing idle.

Fishbowl, Cin7 and spreadsheets track counts, but they do not understand refinery MRO, marine spares or pulp mill consumables where a single missing part stops a multi-million-dollar turnaround. They cannot model criticality, lead times from far-off suppliers, or the reorder points that keep a shutdown on schedule.

So buyers over-order everything to be safe, or discover the one part that matters is on a slow boat.

Why the usual tools struggle in Saint John

  • No concept of part criticality or turnaround readiness
  • Long supplier lead times not modelled
  • Spreadsheets drift out of sync with the storeroom
  • Over-ordering ties up cash in dead stock

What a custom inventory management build changes

Custom inventory software models criticality, lead times and turnaround demand, so reorder points reflect the real cost of a stockout. It links to your ERP (Enterprise Resource Planning), warehouse system and supply chain tools, and feeds dashboards that show readiness at a glance.

Exactly what you get

Inventory software that ranks parts by criticality, sets reorder points from real lead times, supports mobile storeroom counts and shows turnaround readiness, integrated with your ERP and warehouse. You own the code and data.

How to choose a developer in Saint John

Favour a team that has built MRO or spares inventory, not just retail stock control. Ask how they model criticality and lead times, and how they will integrate your ERP. Confirm you own the system.

The benefits
  • Criticality-aware stock and reorder logic
  • Turnaround readiness visible before the shutdown
  • Lead times from distant suppliers modelled
  • Less cash tied up in over-ordered dead stock
  • Storeroom counts that stay in sync
The trade-offs
  • More than a Fishbowl subscription
  • Needs accurate initial data
  • You own maintenance
  • Requires storeroom process discipline
Red flags when hiring (and what to ask instead)
  • !No criticality concept: ask how they rank parts
  • !Ignores lead times: ask how reorder points are set
  • !No ERP integration: ask how it connects
  • !Cannot do mobile counts: ask about barcode support
  • !No ownership: ask for code handover

FAQ

Frequently asked questions

What does custom inventory software cost for a Saint John operator?

Most builds run CAD $40k to $120k, depending on integrations and modelling complexity. A core criticality-aware system starts near $40k.

Why isn't Fishbowl or a spreadsheet enough for refinery MRO?

They track counts but not part criticality, supplier lead times or turnaround readiness, which is what actually prevents a costly stockout. Custom software models the risk, not just the quantity.

Can it prevent a stockout during a turnaround?

Yes, by scoring critical parts and setting lead-time-aware reorder points, it flags gaps well before a shutdown. Readiness is visible on a dashboard rather than discovered on the day.

Does it integrate with our ERP and warehouse system?

Yes, it connects to your ERP and warehouse so stock, costing and location stay in sync. That removes duplicate entry.

How long does an inventory build take?

Plan for 3 to 6 months from discovery to launch. Integration and lead-time modelling drive the timeline.

Do we own the inventory system and data?

Yes, you own the code and data and can host it as you wish. There is no per-seat lock-in.

Can it reduce our dead stock and tied-up cash?

Yes, smarter reorder points cut the over-ordering that piles up dead stock, freeing cash. We tune this against your real usage during the build.

Can crews count stock on mobile devices?

Yes, barcode and mobile counts keep the storeroom in sync, and pair well with a field app for offline capture. Counts update the record directly.

Can we hire inventory software developers in Saint John?

Local IT talent can build it, though MRO and industrial spares experience is worth screening for. Many operators use an agency with an industrial background. Ask for a spares or MRO reference.

What should I have ready before I contact an agency about inventory software?

Bring four things: your SKU count and how stock is identified (plain SKUs, or lots, serials, and expiry dates), every channel and system the software must talk to, a plain-language walkthrough of one order from purchase to shelf to shipment, and a sample export of your current data. With those, an agency can produce a real quote in days instead of a placeholder that doubles later. A one-line brief gets you a demo-sized quote for an operations-sized problem.

What should I prepare before contacting a software development agency?

A one-page brief beats a 40-page requirements document: the business problem in plain words, who will use the system, the 5 to 10 workflows it must handle, the tools it must connect to, and your budget range and deadline driver. You do not need wireframes, a specification, or technical vocabulary; producing those is the agency's job during discovery. Stating a budget range up front is the single best move, because it gets you honest scoping instead of a quote engineered to win the meeting.

What's a realistic timeline for building a custom inventory system?

A usable first version covering receiving, stock movements, scanning, and low-stock alerts ships in 8 to 12 weeks across Digital Heroes inventory builds. Full multi-warehouse systems with Shopify, Amazon, and accounting integrations run 4 to 6 months. Any quote under 6 weeks usually means the vendor has not scoped concurrency handling or data migration.

What are the most common mistakes companies make on inventory software projects?

Three failures dominate: quoting from a one-line brief so real requirements arrive later as change orders, skipping concurrency testing so the first peak season produces oversells, and going live without running the new system in parallel with the old one. All three are process failures rather than coding failures. A two-week parallel run where both systems track the same stock catches most launch disasters before they cost money.

How much should a small business budget for its first custom app or website?

For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.

What does upkeep on a custom inventory system cost per year?

Budget 15 to 20 percent of the build cost per year, so a $50,000 system runs roughly $8,000 to $10,000 annually across Digital Heroes maintenance contracts. That covers hosting, security patches, integration updates when Shopify or Amazon change their APIs, and small improvements. Skipping it is how a channel sync quietly breaks in month nine and corrupts your counts.

Should we start with an MVP or build the full inventory system in one go?

Start with a minimum viable product covering the single most painful workflow, usually receiving, movements, and scanning for one location, then extend in phases. In Digital Heroes delivery experience, phased builds put a working system on the warehouse floor in 8 to 12 weeks and let real feedback shape phase two, while big-bang builds routinely ship features nobody uses. Phasing also spreads the budget across quarters instead of demanding it all up front.

Is custom software more secure than off-the-shelf SaaS?

Neither is secure by default; security tracks the practices of whoever builds and operates the system, not the model. SaaS gives you the vendor's certifications and patching but puts your data in a shared multi-tenant platform on their terms, while custom gives you full control over data residency, access rules, and compliance requirements like HIPAA, with the responsibility sitting with you and your agency. Before hiring anyone for a system holding sensitive data, ask for their security checklist: encryption at rest and in transit, an OWASP Top 10 review, role-based access, and a penetration test before launch.
