Developers reviewing application code and a migration plan

What content marketing means

Content marketing is writing articles, guides and pages that answer the questions buyers search before they are ready to enquire. This makes your business visible and trusted before the first call. GullySales plans this content from the first conversation onward, choosing topics that match real search demand rather than guesses.

For application modernisation and legacy migration companies

Where it usually goes wrong, and what we would do.

  • “Generic transformation content fills every inbox”

    Articles on the benefits of the cloud add nothing for a buyer who already runs a system worth millions in business value. They want to know what goes wrong in the third month of a data migration.

  • “The engineers hold the material and rarely write it”

    A delivery lead knows the traps in a stored procedure rewrite. Without an interviewer and an editor, that knowledge stays in project chats and never reaches a buyer.

  • “Long buying cycles need content for each stage”

    An early reader wants to understand options. A later reader wants a risk checklist for the board. A security reviewer wants a data handling note. One article cannot serve all three.

  • “Content must survive confidentiality review”

    Real detail sells, and real detail is sensitive. Each piece needs a way to keep the learning and remove anything that identifies a client or weakens its defences.

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.

  1. An editorial plan from project debriefs

    A list of topics drawn from finished migrations: what the assessment found, what was surprising, what was verified before cutover.

    Result: A plan where each topic traces to a real project.

  2. Decision guides for the buyer's team

    Guides such as rehost, refactor or rebuild, written plainly, with the questions a buyer should ask each firm.

    Result: A guide the CIO can circulate internally.

  3. A migration risk checklist

    A downloadable checklist covering data, integrations, users, rollback and sign-off, written by the delivery team.

    Result: A checklist a buyer can use even if they never hire you.

  4. A security and data handling note

    A plain document on how data is protected and checked during a move, reviewed by your own security lead.

    Result: A note the information security team can read before the proposal.

  5. A content map linked to the sales stages

    A table that shows which piece serves the early reader, the evaluator and the approver, and where each lives on the site.

    Result: Each piece is tagged to a stage in your sheet.

How the result is measured

  • Pages published
  • Organic traffic
  • Enquiries from content pages

Recorded as a baseline before work starts, so every later report has an honest comparison.

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.

  • No debrief has been written for any past project, so the pieces would repeat what every consultancy publishes.
  • The firm cannot get client approval for even anonymised detail, and the content would have to stay generic.
  • The security note would claim controls the firm cannot yet show, which is worse than saying nothing.

How it works

How the content marketing 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. 1

    Agree the plan

    Topics and formats come from the content strategy and the buyer-question list. The volume goes into the written scope, agreed with you, not into a number quoted on a call.

  2. 2

    Brief and draft

    Each piece starts from its one-page brief and a short conversation with your technical person, recorded if they allow it, so the draft uses their words.

  3. 3

    Check the facts

    Your person marks the draft for accuracy and we correct it. Regulated subjects also go to your own adviser, because restrictions on claims apply to articles as much as to advertisements.

  4. 4

    Publish and distribute

    The piece goes live on your site, then out through the channels where your buyers already are.

  5. 5

    Read the enquiries and adjust

    Results are reported against the baseline recorded before work began. Topics that brought readers but no enquiries are changed or dropped. How often you are reported to is agreed in writing.

Where this fits

Three pieces of sales work, in this order.

This work sits inside sales process design, at stage 0, foundation. The audit comes before it, and sales management keeps it running.

  1. 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.

  2. Step 2 · you are here

    Sales process design

    One written way to sell, from first enquiry to repeat order.

    Start here if every salesperson sells differently.

  3. Step 3

    Sales management

    A target, a review routine and someone who owns the number.

    Start here if the team has targets and no routine.

FAQ

Questions owners ask before they call.

Not here? More answers, or ask on WhatsApp.

Tell us what you need
How many articles does a modernisation firm need?
Enough to cover each stack and each stage of the buyer's thinking, in depth. A few strong pieces on real migrations do more than a large archive of general posts. Add pieces when a buyer asks a question you have not yet answered.
Should we gate our checklists behind a form?
Gate only what a buyer would trade a business email for, and keep the rest open. A checklist that spreads inside a company by forwarding is worth more ungated than a few captured addresses.
Who should review technical content before it goes out?
The engineer who did the work checks accuracy, and someone senior checks it against client agreements. A short sign-off step stops a good article from becoming a confidentiality problem.
Should we write for the CIO or the engineer?
Write each piece for one role and say which in the title. The CIO wants risk and cost, while the architect wants dependency and test detail. One piece aimed at both satisfies neither, so keep them separate.
How much does it cost?
There is no price list, because the work differs by business. The fee is scoped after we have read your brief and spoken to you, and put in writing before anything starts, split into our time, your media spend and production.
How long is the contract?
The term is agreed in writing after we have spoken, along with the fee and the reporting. It is never a default twelve months, and renewal is decided on the numbers against the baseline recorded at the start.
How soon will we see results?
It depends on the trade, the channel and what is already in place. After we have read your brief and spoken to you, we say what we would expect to move first and how it will be measured against the baseline. Nothing here is guaranteed.
Who will actually do the work?
The person you speak to before anything starts. We work from one office in Nagarbhavi, Bengaluru, with no account managers in between.
What do you need from us?
Your brief, and a conversation. After that, access to whatever this work touches, such as your website, your accounts or your enquiry record, and time with the people who handle your enquiries.
What if we are not happy with the work?
Tell us and the plan changes. Everything is reported against the baseline, so a number that is not moving is visible to both sides. The term is in your written scope, and the refund and cancellation policy sets out the rest.
