Application modernisation and legacy migration companies · CRM
Keep a long enterprise sale in view when the champion changes roles.
A CRM for a modernisation firm records accounts, the people on each buying committee and the history of a sale that can run for more than a year. GullySales works on the fields, stages and habits that make a CRM useful for a small enterprise sales team.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

What CRM means
A CRM is the record where every enquiry, call and quote is kept against a customer, replacing separate notebooks, spreadsheets and memory. GullySales sets up or cleans an existing CRM and reports from it by enquiry outcome rather than by activity logged.

For application modernisation and legacy migration companies
Where it usually goes wrong, and what we would do.
“Accounts matter more than leads”
The unit of sale is a company with several roles in play. A CRM built around single contacts misses the architect who advised, the security reviewer who objected and the champion who left.
“Stages must match an assessment-led sale”
Stages such as assessment offered, assessment done, plan presented, security review and contract describe the real path. Generic stages like proposal sent hide where the deal is stuck.
“Notes get lost when engineers join the calls”
A solutions architect on a call hears the technical truth. If those notes live in a personal notebook, the next conversation starts from zero and the buyer repeats themselves.
“A champion who moves on takes the sale with them”
If the CRM holds only the champion's number, the firm loses the account when the role changes. The record needs the other roles and a plan for meeting them.
What we do
What we deliver for application modernisation and legacy migration companies.
Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.
An account-centred CRM set-up
Account records with the legacy stack, hosting, regulator context, the roles on the committee and the next decision date.
Result: Each account page shows system, roles and next date.
Sales stages built for assessments
Stages and exit rules agreed with the sales and delivery leads, so everyone moves a deal on the same evidence.
Result: A stage list where each stage has a written rule.
A technical notes field and template
A short template for engineers to log what they learned on a call about the system, data and integrations.
Result: Every technical call leaves a note in the account.
A partner and source field
Fields for the partner involved, the source of the introduction and any joint plan.
Result: You can list accounts by partner and by source.
A weekly-free review routine in the team meeting
A short agenda to go through accounts that have not moved, in the meeting the team already holds.
Result: A list of stalled accounts with a named owner for each.
How the result is measured
- Enquiries logged in the CRM
- Data completeness
- Reports generated from CRM data
Recorded as a baseline before work starts, so every later report has an honest comparison.
Fields worth keeping
Keep these fields on each account and each contact.
- Legacy stack and version
- Filled by the sales lead after the first call and checked by an engineer, so the right case study and engineer are matched later.
- Trigger for the project
- Support end, audit finding or hosting contract, entered at discovery, which shows when a buyer's budget is likely to open.
- Roles in the buying committee
- Sponsor, architect, security reviewer and finance contact, with the date each was last spoken to, so a missing role is visible.
- Assessment status
- Offered, scoped, signed or delivered, set by the delivery lead, so the pipeline shows what follows a finished assessment.
- Source or partner involved
- A cloud partner, a former client or a stack page, entered at creation, so the firm can see where good accounts come from.
Who it is for
This is written for these application modernisation and legacy migration companies.
- Banks and NBFCs running core and loan systems built decades ago
- Insurers with policy administration and claims platforms on old stacks
- Hospital groups with a hospital information system nobody wants to touch
- Manufacturers on ageing ERP customisations and plant-floor software
- Logistics and supply chain firms with in-house dispatch and tracking applications
- Public sector bodies and PSUs with tender-led replacement projects
- Software product companies with a monolith that slows every release
- Mid-sized companies moving data centres to AWS or Azure
Not for
It is not the right fit if.
- The firm has few accounts and a spreadsheet already shows them all, so a new system would be more work than the sale.
- No one will write engineer call notes into it, and the technical field would stay empty.
- You expect a CRM to fix a sales process that has no defined stages.
How it works
How the CRM work runs
The work itself, in order. How an engagement starts, from your brief to a written scope, is set out on our method page.
- 1
Map the sales process
We sit with the people who sell and write down how a deal moves from enquiry to payment, including where it stalls.
- 2
Agree stages, fields and owners
Each stage gets a name your team already uses and a proof that the deal has left it. We agree which fields are required at which stage, and who may change what.
- 3
Build on a copy
Pipeline, fields and views are built on a trial copy where the CRM offers one, or in a separate pipeline where the plan allows. Live work stays untouched.
- 4
Connect channels, then switch on automations
Channels are connected first. Each automation is then switched on separately, so a misfiring rule is easy to find.
- 5
Test with real deals
The people who will use the CRM run open deals through it. Gaps are fixed before the whole team switches over.
- 6
Switch over and trim
Once real use shows which fields stay empty and which stages nobody uses, those are cut and the handover record is updated.
Where this fits
Three pieces of sales work, in this order.
This work sits inside sales management. A target, a review routine and someone who owns the number.
Step 1
Sales audit
Find where deals are being lost and what to fix first.
Start here if you cannot say where orders are lost.
Step 2
Sales process design
One written way to sell, from first enquiry to repeat order.
Start here if every salesperson sells differently.
Step 3 · you are here
Sales management
A target, a review routine and someone who owns the number.
Start here if the team has targets and no routine.
