Buyer’s guide
How to choose production planning softwarefor a garment factory.
A 13-point checklist for managing directors, COOs and planning heads. Use it with any vendor, including us.
By Ayan Barua, CEO, Diverzent · 9 min read · Updated November 2026
The short answer
What to look for, in four sentences.
The right planning software for a garment factory plans the floor the way it actually runs: finite line capacity, SMV, learning curves and suborders. It keeps materials, T&A and finishing in step with the sewing plan. And it shows what each plan earns before you commit it.
Judge every vendor on your own order book, not on a demo dataset.
Before you buy
Why most planning projects disappoint.
Most factories buy planning software to stop missing ship dates. Most still plan in Excel two years later. The software was chosen on a demo, the planners found it slower than their spreadsheet, and the plan on screen drifted from the plan on the floor.
The fix is to buy against the realities of a sewing floor, not a feature list. The checklist below is grouped the way a planning head thinks: the floor, the supply, the money and the enterprise.
The checklist · 1 of 4 · The floor
Does it plan the floor as it really runs?
Thirteen things to check, and what to ask the vendor. The first four decide whether the plan on screen is the plan on the floor.
- Finite capacity
- A plan that ignores line hours, holidays and shifts looks fine until the third week of the month. Ask the vendor: “Show me a line that is overloaded. What does the system do?”
- SMV and learning curves
- Day-one efficiency on a new style is not day-ten efficiency. Plans that skip the curve promise output the line cannot give. Ask the vendor: “How does a repeat style on the same line change the plan?”
- Suborder granularity
- Buyers ship by colour, size break and destination. Planning at style level hides the split that misses the boat. Ask the vendor: “Plan one PO with four delivery splits, live.”
- Many planners, one board
- When two planners move the same order, one of them is working on a plan that no longer exists. Ask the vendor: “What happens when two of us edit the board at once?”
The checklist · 2 of 4 · The supply
Does it keep supply in step with the plan?
A sewing date is only as good as the fabric, trims and finishing behind it.
- T&A and critical path
- If fabric approval is late, the sewing date is fiction. The plan should know before the planner does. Ask the vendor: “Can a missed T&A milestone stop an order being loaded?”
- Material readiness by process
- Cutting, printing and embroidery starve sewing more often than capacity does. Ask the vendor: “Which line will starve next week, and why?”
- Finishing
- Many plans are won in sewing and lost in finishing and packing, three days before shipment. Ask the vendor: “Show me the finishing plan that follows this sewing plan.”
The checklist · 3 of 4 · The money
Does it decide with money?
On-time is the minimum. The question is what each plan earns.
- What each plan earns
- Two plans can both ship on time and earn very different money. Most systems cannot tell you which is which. Ask the vendor: “Compare two plans for me in contribution, not just dates.”
- Overtime as a decision
- Overtime is often bought because it feels safer, not because it saves a shipment. Ask the vendor: “When does the plan recommend overtime, and what does it cost?”
- Explainable results
- A planner will not sign a plan they cannot explain to the MD. “The AI decided” is not an answer. Ask the vendor: “Run it twice on the same data. Do I get the same plan? Why this one?”
The checklist · 4 of 4 · The enterprise
Can it run as enterprise software?
What IT, finance and the board will ask before anyone signs.
- ERP connection
- Retyping orders into a planning tool is where errors and delays begin. Ask the vendor: “Show me the documented API, and a client using it today.”
- Group planning
- Groups lose money when each unit optimises its own plan in isolation. Ask the vendor: “Can I move work between factories on one board?”
- Data and go-live
- IT will ask where the data lives and who changed what. The board will ask how long until it is live. Ask the vendor: “Is my data in its own database? Is every change logged? What is the go-live plan, week by week?”
How to run the demonstration
Send last month’s real order book and line list in advance. Ask your planning head, not IT, to drive for twenty minutes. Change one order mid-demonstration: a date, a quantity, a cancellation. Ask for the plan’s cost, not only its dates. Then ask to speak to a planner at a live client.
Warning signs
The demonstration only ever runs on the vendor’s own data. “AI” that cannot say why it chose a plan. Finishing and packing are “phase two”. Integration means a CSV upload every morning. No one can give you a go-live date.
ProactivePlan
How ProactivePlan answers the checklist.
ProactivePlan is our AI planning platform for apparel. Here is our answer to each group, so you can hold us to it in a demonstration. Running today in Bangladesh at New Asia Group, Ragadi Textile and Northern Group.
- The floor
- Finite hour capacity per line, suborder-level planning, and learning curves that carry across similar work automatically. Every planner works on one live board; a move made on a board that has since changed is refused, not overwritten.
- The supply
- T&A readiness gates the plan. Supply flow is tracked per suborder and per process, so you see which process will starve sewing before it does. A dedicated finishing board follows the sewing plan.
- The money
- Every plan is priced in contribution against labour and overtime, at your own rates. Delivery comes first, then money. A complete alternative plan arrives in minutes. Same inputs, same plan, every time.
- The enterprise
- Orders arrive from any ERP with API capability through our documented API. One board across your factories. Your own database, with every edit logged by name. Typical go-live: three months.
FAQ
Questions buyers ask.
What is the best production planning software for a garment factory?
The one that plans at line, style and suborder level with finite capacity and learning curves, gates the plan on T&A and material readiness, covers finishing, connects to your ERP, and shows the financial outcome of each plan. Test it on your own order book before you buy.
What is the difference between PPC, APS and planning software?
PPC (production planning and control) is the department and its process. APS (advanced planning and scheduling) is software that schedules against real constraints. Modern apparel planning platforms combine APS with T&A, supply tracking and, increasingly, financial evaluation of each plan.
When does a factory outgrow Excel for planning?
Usually when more than one planner edits the plan, when orders split by delivery, or when nobody can say what a change will cost. Excel records a plan well; it cannot test alternatives or keep many planners in step.
Do we need to replace our ERP?
No. The ERP records what happened; planning software decides what should happen. A planning platform should take orders from your ERP through an API.
How long does implementation take?
Ask for a week-by-week plan. For ProactivePlan, typical go-live is three months, including master data, ERP connection and planner training.
Will AI planning take control away from our planners?
It should not. Good AI planning drafts and prices alternatives; the planner chooses, applies and can reverse. Ask to see who approves a plan, and where that is logged.
Is cloud planning safe for factory data?
Ask whether your data sits in its own database, which region hosts it, how backups work, and whether every change is logged by name. ProactivePlan gives each client its own database.
