ERP Pricing, Cost Drivers and 2026 Rules
ERP AMC, support plans and renewal uplifts: how the yearly bill grows
How ERP AMC and support fees are charged in India, what renewal uplifts do to a five-year cost, and how to negotiate a cap before you sign.
After the first year, the ERP bill is driven by two things: the support or AMC fee and the renewal uplift, the percentage by which the vendor raises the price when the term ends. An AMC on a perpetual licence is usually a percentage of the licence value; a SaaS subscription has support built in but may rise at each renewal. A 10% yearly uplift on ₹5 lakh a year adds more than ₹1 lakh a year by year three, so the time to fix the uplift is before signing, not at renewal. This guide shows the arithmetic with illustrative figures.
This guide is part of the overview of ERP software pricing in India.
What AMC and support usually include
| Item | Perpetual licence + AMC | SaaS subscription |
|---|---|---|
| Software updates and new versions | Included only while AMC is paid | Included |
| Statutory updates (GST changes, new return formats) | Usually included while AMC is paid; check | Usually included |
| Helpdesk | Included at a stated level | Included at a stated level; premium tiers extra |
| Hosting, backups, security | Your responsibility | Vendor's responsibility, as stated in the contract |
| Partner support for your configuration | Often a separate partner AMC | Often a separate partner support plan |
| Custom code maintenance | Usually extra | Usually extra |
Two contracts are common: one with the software vendor and one with the implementation partner for functional support. Make sure you know which one answers when an e-invoice fails at 9 pm on the last day of the month.
AMC as a percentage of licence value
For on-premise or desktop licences, AMC is typically quoted as a percentage of the current list price of the licences. An illustrative range is 15–25% a year. Two details matter:
- Base: is it a percentage of what you paid, or of today's list price? If the list price rises, your AMC rises with it.
- Lapse and reinstatement: if you stop paying AMC and later want updates, some vendors charge back-AMC for the missed years or a reinstatement fee.
Worked example: AMC over five years (illustrative)
Licences for 15 users cost ₹6,00,000. AMC is 20% a year from year 2, calculated on the list price, which rises 5% a year.
| Year | List price base | AMC at 20% |
|---|---|---|
| 2 | ₹6,30,000 | ₹1,26,000 |
| 3 | ₹6,61,500 | ₹1,32,300 |
| 4 | ₹6,94,575 | ₹1,38,915 |
| 5 | ₹7,29,304 | ₹1,45,861 |
| Total AMC | ₹5,43,076 |
Five-year cost = ₹6,00,000 licence + ₹5,43,076 AMC ≈ ₹11,43,000, before servers, backups and partner support. AMC almost doubles the licence cost over five years.
Renewal uplifts on SaaS
A SaaS contract may hold the price for the first term (often one or three years) and then allow an increase. Common wordings:
- a fixed cap, for example "not more than 7% per renewal";
- a link to an index such as consumer price inflation;
- "the vendor's then-current list price", which has no cap at all;
- loss of an introductory discount at the first renewal, which can look like a large one-off jump.
Worked example: what uplifts do to five years (illustrative)
A ₹4,00,000 a year subscription, with the price increased at each annual renewal:
| Uplift | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | Five-year total |
|---|---|---|---|---|---|---|
| 0% | ₹4,00,000 | ₹4,00,000 | ₹4,00,000 | ₹4,00,000 | ₹4,00,000 | ₹20,00,000 |
| 5% | ₹4,00,000 | ₹4,20,000 | ₹4,41,000 | ₹4,63,050 | ₹4,86,203 | ₹22,10,253 |
| 10% | ₹4,00,000 | ₹4,40,000 | ₹4,84,000 | ₹5,32,400 | ₹5,85,640 | ₹24,42,040 |
The difference between a 5% cap and a 10% uplift is about ₹2,32,000 over five years on this illustrative base. If an introductory discount of 20% also ends at the first renewal, the year-2 price could jump far more.
How to measure and negotiate an uplift
- Measure it: uplift % = (renewal quote − current annual price) ÷ current annual price × 100. A renewal of ₹4,80,000 on ₹4,00,000 is a 20% uplift.
- Check the contract: is there a cap? Is the vendor within it?
- Clean up seats and modules: remove users who have left and modules nobody uses. Get a usage report from the admin console.
- Ask for a discount or a cap for the next term, in exchange for a longer commitment if that suits you.
- Know your alternative: a credible alternative quote and a realistic migration estimate strengthen your position.
The ERP renewal uplift and negotiation calculator works out the reduction from a negotiated discount and dropped seats. For example (illustrative), on a ₹4,80,000 quote, 8% off plus three dropped seats at ₹19,200 each saves ₹38,400 + ₹57,600 = ₹96,000, bringing the bill to ₹3,84,000.
Support levels and what to ask
| Question | Why it matters |
|---|---|
| What are the response and resolution times by severity? | A stopped invoicing process at month-end needs hours, not days |
| What hours and languages is support available in? | Night and weekend billing or dispatch may need cover |
| Is there a named account manager or escalation path? | Repeated tickets need escalation |
| Are statutory changes (GST, payroll) delivered as part of support? | Return formats and e-invoice schemas change |
| What are the service credits if the SLA is missed? | Credits give the SLA teeth |
The SaaS contract guide covers SLA wording in more detail. To see how these yearly costs combine with implementation over time, use the 3–5-year TCO guide, and compare cloud and on-premise in cloud vs on-premise ERP.
FAQ
Can I stop paying AMC and keep using the software?
With most perpetual licences you can keep using the version you have, but you lose updates and support, including statutory updates for GST or payroll changes. That can make the software unusable for compliance within months.
Is GST charged on AMC?
Yes, support and maintenance services generally attract GST at 18%, which a registered business can usually claim as input tax credit.
Is a multi-year price lock a good idea?
It removes uplift risk but makes leaving more expensive. It suits a system you are confident in, with stable user numbers.
