Buy on how the vendor models an escalation clause, not on the dashboard. Ask two finalists for a paid discovery phase and compare the written specifications. Expect $80,000 to $160,000 for a first release covering agreements, escalations and termination control, and $200,000 to $500,000 for the full platform. A firm that stores escalation as a percentage field will cost you thirty years of wrong payments.
Every site portfolio carries a number nobody has counted: rent still leaving the building each month for structures that were decommissioned years ago. You will not find it in the payment file, because the payment file is where it hides. The equipment came down, the project closed, the termination notice missed its window, the term auto renewed, and the payment kept running to a landlord in a market you no longer serve.
That is what makes this category hard to buy. Any vendor can demonstrate a clean site list against clean data. What you are actually purchasing is agreement between a scanned lease and a payment run, across a portfolio where the terms were drafted by twenty different lawyers over thirty years and half the amendments arrived through acquisitions. None of that is visible in a demo, and the thing that decides whether the project works is not the software at all. It is whether the lease language ever became structured, testable data.
What a site lease management development company actually does
The visible build is a site register, a document viewer and a payment schedule. You will see it in week three and it is not where these projects fail.
The rest is the work. Someone turns agreement language into structured terms and holds the document lineage, so a site with a 1998 ground lease, a 2004 assignment, three amendments, a memorandum of lease and a later easement computes its current effective terms rather than relying on whoever last read the file. Someone models escalation as a rule with a type, a frequency, an anniversary basis, an index reference where one applies, floors, caps and a rounding convention, because rounding is a real source of landlord dispute. Someone makes lifecycle status drive payments, so marking a site for decommissioning immediately creates a termination task with the notice date calculated from the clause and an owner attached. Someone builds payee controls: one payee record per landlord entity, duplicate detection across payee and site, and a hold when a change of ownership letter arrives, because fraudulent change of payee requests target exactly the manual process you are replacing.
Then the part that is not code. Extraction models can read the scanned lease and the amendment chain and propose values for the standard terms, which turns a two year manual review into a few months of confirmation. It does not remove the human confirming every money term against the linked page. An escalation clause misread by a model becomes decades of wrong payments.
What it really costs in 2026
These bands come from contract portfolio delivery, not a generic app estimate.
| Project tier | Cost | Timeline |
|---|---|---|
| First release: site and agreement model with amendment lineage, abstracted terms, escalation and payment engine, termination control | $80,000 to $160,000 | 14 to 20 weeks |
| Full platform: colocation and revenue share billing, deployment milestones, permit and structural records, landlord portal, accounting integration | $200,000 to $500,000 | 9 to 15 months |
| Portfolio assembled through acquisitions across several jurisdictions and indexation regimes | $500,000 to $900,000 | 15 to 24 months |
| Support, rule changes and portfolio growth | 15 to 20 percent of build a year | Retainer |
Two line items vanish from most quotes. The first is abstraction. Thirty thousand documents is a programme in its own right even with extraction help, and it is priced in reviewer hours rather than developer hours. Vendors leave it out because it makes the number look better, and buyers read the missing line as the software being cheap.
The second is lease accounting. Your controller will not accept an approximation of the ASC 842 or IFRS 16 treatment, so the posting interface becomes a separate negotiation with finance. Ask whether the quote covers the accounting treatment or only a payables file, because those are months apart.
Signals you have found a strong partner
- They model the agreement before quoting. Site, structure, agreement with lineage, effective term computed from that lineage, escalation rule, payment schedule, lifecycle status driving payments.
- They raise the awkward escalator early. An index linked clause with a floor, a cap and a lagged base month should come up within ten minutes, unprompted.
- Rounding convention is their question, not yours. It is the detail that turns into a landlord letter, and knowing that is a mark of having built financial terms before.
- Abstraction is a workflow, not data entry. Each term carries a confidence, a reviewer and a link to the page it came from, with a second pass on anything touching money.
- They name your enterprise resource planning (ERP) system and the direction of data flow. A payables interface and a lease accounting treatment are two different problems, and a serious firm separates them out loud.
- A change of payee request creates a hold, not an update. Payment fraud in this space works through a plausible letter and a helpful administrator.
- You own the code and the abstracted data from the first commit. The abstraction output is often the most valuable thing the project produces.
Red flags that should end the call
- Escalation is a percentage field. A large share of any real portfolio escalates on an index, a greater of formula, or a structure that changes at renewal.
- Amendments are attachments on a site record. The effective term has to be computed from the instrument chain, or your system will confidently show terms that were superseded in 2011.
- Nobody asks how the portfolio was assembled. Drafting traditions from three acquisitions do not normalise cleanly, and the archetype count is most of the abstraction estimate.
- They propose replacing Sitetracker on day one. Deployment programme management is a solved problem you already pay for. Buying it again is spending on the part that works.
- The quote has one line for the whole engagement. Without abstraction, accounting and migration broken out, you are comparing a number rather than a scope.
What to ask on the first call
- Model a site with a 1998 ground lease, a 2004 assignment, three amendments and a memorandum of lease. Where do the current effective terms come from?
- Show me an index linked escalator with a floor, a cap and a lagged base month, and tell me your rounding convention.
- A site is marked for decommissioning this morning. What happens to the payment, the termination task and the notice date?
- A published index is revised. Which sites recalculate, and does anything change without a human seeing a variance list?
- A colocation amendment is signed by a construction manager. What starts the invoice, and who no longer has to send an email?
- How is a landlord revenue share obligation derived from those same amendments rather than calculated separately by another team?
- Which payables interface do you write into, and does the quote include lease accounting treatment or only the payment file?
- How many reviewer hours does your plan assume for abstraction, and who supplies them, us or you?
- Who owns the repository, the hosting accounts and the abstracted lease data, and will that be in the contract before kickoff?
How to decide without guessing
Do not pick from proposals. Pay your two strongest candidates for a short discovery phase against the same brief, and buy the output rather than the pitch. What you should hold at the end is a written specification you own: the agreement and lineage model, the escalation rule types your portfolio actually contains, the lifecycle and termination controls, the payee controls, the accounting posting design, and a phased plan with abstraction costed in reviewer hours. Take that document to every firm on your shortlist, including ones you have not met yet. The quotes become comparable for the first time.
Digital Heroes runs this way by default, with a product requirements document first and contracting through an India LLP, a US LLC or a UK LTD so intellectual property assigns under your own law. Say plainly where we are wrong for you: under roughly 500 sites, or where your real problem is running a build programme rather than lease economics, Sitetracker or Tarantula will serve you better than anything custom, and we will tell you so on the first call.

Frequently asked questions
How much does it cost to hire a tower site lease management software company?
A first release with the agreement model, abstracted terms, escalation engine and termination control runs $80,000 to $160,000 over 14 to 20 weeks. The full platform with colocation billing, revenue share, landlord portal and accounting integration runs $200,000 to $500,000 across 9 to 15 months. What moves you up a band is the number of drafting archetypes in the portfolio, not the number of sites.
How long does the abstraction programme take on a large portfolio?
With extraction models proposing values and reviewers confirming each money term against the source page, most portfolios clear in a few months rather than the two years a fully manual review takes. The pace is set by reviewer availability, not by software. A practical sequence is to abstract rent, escalation, term, renewal, notice and revenue share first, then return for the wider clause library later.
Who owns the abstracted lease data if an agency builds the system?
You should, in writing, before the first commit. The abstraction output is frequently worth more than the software, because it is the asset that makes diligence fast the next time you buy or sell a portfolio. Insist on the repository, the cloud accounts and the structured lease data sitting in accounts you control, with an export you have actually tested rather than one described in a contract.
What happens if a landlord disputes an escalated payment?
In a well built system it becomes a two minute answer: the clause as abstracted, the linked page of the original instrument, the index value used with its base month, the rounding convention applied and the arithmetic, all on one screen. Where escalation is stored as a single percentage, the same dispute becomes a document hunt, and portfolios usually settle rather than spend the week proving they were right.
Can we keep Sitetracker and still build a lease system?
Yes, and for most portfolios that is the right shape. Sitetracker is strong at deployment programme management, which is a different problem from lease economics. The build holds the agreement model, escalations, lifecycle status and payment controls, and the two systems share the site identity. Replacing a deployment tool that works is spending money on the half of the process that is not currently losing you anything.
Should we build if we are acquiring portfolios rather than operating one?
That is one of the stronger cases. When you compete to buy portfolios, the speed and accuracy of diligence abstraction is a commercial advantage rather than back office work. Being able to load a seller's document set, propose terms, flag the escalators that do not fit your model, and produce a rent roll you trust in days changes what you can bid on and how confident the bid is.
What is the difference between lease administration software and a custom build?
Packaged lease administration assumes a normalised portfolio: one lease per property, a rent amount, an escalation rate. Site portfolios break each of those assumptions, because a structure carries a ground lease underneath and several tenant agreements on top, escalators are formulas rather than rates, and the amendment chain decides which terms are live. A custom build models the chain and computes terms, rather than storing whatever the last administrator typed.
How does the system stop payments on a decommissioned site?
Payments derive from the site lifecycle status rather than sitting in a separate file, so marking a site for decommissioning immediately creates a termination task with the required notice date calculated from the clause, an owner and an escalation path. If the notice date passes with no notice recorded, the failure is reported with the cost of the missed window attached. A number on a missed task changes behaviour faster than a reminder.
Can one system hold both deployment milestones and lease obligations?
It can, and the reason to do it is a question your chief financial officer will ask: what committed rent is running against sites that are not yet generating revenue. Deployment tools cannot answer it because they do not hold the money, and lease systems cannot answer it because they do not hold the schedule. Attaching both timelines to one site record makes the dependency visible and the answer routine.
Do we need a developer with telecoms experience specifically?
You need one who has modelled financial contract terms before, which is the transferable skill. Telecoms vocabulary can be learned in a fortnight of interviews with your lease administrators. What cannot be picked up on the job is the instinct to ask about effective dates, index lags and computed terms before drawing a single screen. Ask for a portfolio system they built where the contract language drove the payments.
How much does a custom ERP cost for a small business?
A small-business ERP covering two or three core modules typically runs $40,000 to $120,000, with inventory, ordering, and accounting sync being the usual starting set. Across 2,000+ Digital Heroes projects, integration count and user roles drive cost far more than screen count. A full mid-market ERP with six or more modules usually lands between $150,000 and $400,000.
What should I prepare before contacting an ERP development agency?
Bring a list of your current tools and spreadsheets, a rough map of how an order or job moves through the company today, your user count by role, and the three problems costing you the most hours. You do not need a formal specification; a good agency writes that with you during discovery. Companies that arrive with those four things typically cut two to three weeks off scoping in our experience.
How do I vet an agency for an ERP project?
Ask to speak with two clients who have been running an ERP the agency built for at least two years, because ERP quality shows up in year two, not at launch. Then ask for their data migration plan, their module rollout sequence, and the named senior engineers who will be on your project. An agency that leads with screen designs instead of process mapping is a red flag for ERP work.
Should I pick Microsoft Dynamics 365 Business Central or build a custom ERP?
Pick Business Central if you already live in the Microsoft stack, your processes are close to standard, and around $80 per user per month for Business Central Essentials stays affordable at your headcount. Build custom when your revenue-driving workflow, such as custom manufacturing steps or unusual pricing logic, would need heavy extension work anyway. In our experience, once Dynamics customization quotes pass about $100,000 the custom option deserves a serious side-by-side.
How long does custom ERP development take?
Plan on 3 to 4 months for the first working module and 6 to 12 months for a full multi-module rollout. In Digital Heroes delivery experience the schedule risk is data migration and integration testing, not feature coding, so we stage go-lives module by module instead of one big-bang launch.
Can a freelancer build an ERP, or do I need an agency?
An ERP is too wide for one person: it needs backend, frontend, database design, integrations, QA, and someone mapping your business processes. A solo freelancer can extend an existing ERP or ship one small internal tool, but full ERP builds by single developers are the most common rescue scenario Digital Heroes takes on. If budget is tight, shrink the scope to one module rather than shrinking the team below three or four people.
What mistakes kill ERP projects most often?
The three we see most in rescue work at Digital Heroes: recreating the old system's broken process in new software, launching everything at once instead of module by module, and having no single internal owner with authority to decide. A fourth is skipping the parallel run on data migration to save two weeks, which trades a short delay for months of distrust in the numbers. None of these are technical failures, which is why vendor selection should weigh process discipline over demo polish.
Who can build a custom ERP software system?
Digital Heroes builds custom ERP software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other ERP software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
