An annual budget is critical for business growth and should include projected expenses and income along with how expenses will be funded from income sources. The budget will need adjustments throughout the year to reflect reality. Before investing or spending, businesses should consider the likelihood and timing of returns. Increasing revenue can be done by adding complementary services or products, adjusting shipping charges, using coupons, and incentivizing sales partners. Reducing costs involves using VoIP phones, recycled printer cartridges, going paperless, using technology for meetings, and sharing resources with other small businesses. Profit is key, so managing costs and revenue is important.
