How to start an SMS marketing business

An SMS marketing provider builds and runs text message programs for local businesses that want a direct line to repeat customers. Most of the work is unglamorous: configuring a texting platform, writing opt-in language, placing sign-up prompts at the counter and on receipts, scheduling a few short messages, and reading the opt-out rate after every send. The main decision is whether you resell a platform under your own account or work inside each client's account. The real constraint is consent. Text messages are governed by federal telemarketing and anti-robocall rules plus carrier registration requirements, so a list built carelessly can trigger blocked numbers, carrier fines, or legal claims that dwarf any fee you charge.

The business in one offer

Who it serves

Independent restaurants and cafes with steady regulars, a weekday slow period, and an owner who already posts specials on social media but sees little response. They pay because a short text about a Tuesday deal reaches people who chose to hear from them, and because they have no time to learn carrier registration or consent wording themselves.

What to sell first

A 90-day text club setup and management package: carrier brand and campaign registration help, a keyword and QR-code opt-in flow, table tent and receipt copy, a welcome message with clear stop instructions, and two scheduled promotional texts per month with a short results note. Excluded: buying or importing lists, cold texting, daily blasts, and any message sent to a number without documented opt-in.

Two messages a month on one platform is easy to quote and hard to get wrong. The opt-in materials are reusable across restaurants with small edits, the send calendar fits in a single shared sheet, and owners can see redemptions at the register instead of trusting an abstract dashboard.

What could it cost to start?

This is an original example budget for the limited pilot described above. It is not a researched market average or a complete quote for every location.

Illustrative setup allowances · USD
Item to priceExample allowance
Texting platform plan and per-message credits, three months$270.00
Carrier brand and campaign registration fees allowance$60.00
Printed table tents and counter signs for two pilot clients$120.00
Short consultation with a lawyer on consent wording$400.00
Business registration and bank account allowance$150.00
Professional liability insurance quote allowance$300.00
Example total$1,300.00

What this assumes—and excludes

Assumes you already have a laptop, a smartphone for testing sends, and basic copywriting skills. Excludes paid ads, office space, owner pay, and per-client message volume above the pilot plan. Platform pricing, registration fees and insurance costs change often, so get current quotes before you set your monthly fee.

Collect actual supplier, insurance and local-authority information. Add a reserve for delays and unexpected costs; the example total is not a funding recommendation.

How the unit economics work

At an assumed $350.00 per monthly client and $45.00 in direct costs, contribution is $305.00 before monthly fixed costs, owner pay and taxes. With 4 all-in working hours per unit, that is $76.25 per delivery hour before those deductions. These inputs illustrate the arithmetic; they do not establish a market price or expected earnings.

The example also allows $110.00 in monthly fixed costs. Include unpaid acquisition and administrative time when deciding whether the offer is worthwhile.

Try your own numbers

These are editable planning assumptions, not prices we have verified. Calculations stay in your browser.

Contribution per unit$305.00
Monthly operating result$2,940.00
Monthly break-even units1
Startup funding gap$1,300.00

Operating result = (price − direct cost) × units − monthly fixed costs. Before owner pay, taxes, financing and startup recovery. At these inputs, delivery requires 40 hours per month, plus any work not included in your per-unit estimate. Sales volume is a scenario, not a forecast.

How to find the first customers

Test a small offer before scaling traffic. Record the source of each enquiry, whether it fits the offer, and whether the buyer pays.

  1. Visit restaurants during the mid-afternoon lull, ask the owner which weekday is slowest, and show a printed mockup of a table tent with their name and a sample opt-in keyword. Leave a one-page price sheet instead of pushing for a decision.
  2. Offer one restaurant a reduced first month in exchange for permission to describe the setup, without naming numbers, to other owners. Record how many sign-ups the counter sign produced each week so you have your own honest figures.
  3. Ask point-of-sale and menu printing vendors which of their restaurant clients want a repeat-visit tool. Propose a simple referral thank-you, and disclose any fee to the restaurant.
  4. Run a short talk for a local restaurant association or chamber food group on what consent rules mean for texting customers. Collect follow-up contacts only through a written sign-up sheet.

What to validate before spending more

  1. Pay for an hour with a lawyer to review your opt-in wording, welcome message, stop handling and record keeping. Save their notes and update templates before signing a second client.
  2. Complete carrier registration for one pilot client and time how long approval takes. If it runs weeks, build that delay into your onboarding schedule and contract.
  3. Track opt-in count, opt-out rate after each send, and coupon redemptions at the register for the first 60 days. If opt-outs rise sharply after a send, cut frequency before adding clients.
  4. Check whether your city or county requires a general business license for a home-based marketing service and note any sales tax rules on bundled printed materials.

The operational catch

Restaurant owners often hand you an old spreadsheet of customer phone numbers and ask you to text them all. Those numbers rarely came with written consent for marketing texts. Importing them is the fastest way to get the client's number filtered by carriers or sued. Put a clause in your contract that you only message numbers collected through your own opt-in flow.

A practical way to fund the first step

Charge the first month and the setup fee upfront, and pick a platform with monthly billing and pay-as-you-go message credits. The first client's payment covers registration fees and printing, so you never carry message costs on your own card for long.

Separate cash already available from money still to earn. Count only proceeds after direct expenses, and do not spend customer funds needed to fulfill their existing orders.

Questions before you start

Can I text customers who gave their number for online orders?

Not for marketing unless they separately agreed to receive promotional texts. An order confirmation is transactional. Add a clearly worded, unchecked opt-in box at checkout and keep a record of when and how each person agreed.

How many texts per month is too many?

There is no single number, but most restaurants do not have enough news to justify more than a few. Watch the opt-out rate after each message. A spike tells you the list is tiring faster than the promotions are worth.

Should I work in my account or the client's account?

Working inside a client-owned account keeps the list and the consent records with the business if you part ways, which makes owners more comfortable. Reselling from your own account is simpler to bill but makes you responsible for every client's sending behavior.
